STRATEGIC GOALS
General goals of the Materials Science Department include competitive Research &
Development and Advanced Training in the field of new materials and their industrial
applications.
Theoretical and experimental studies are carried out in several fields such as ionic
conductors, electrochemistry, molecular electronics, laser, molecular modelling,
insulator oxides, non-linear optics, polymers, semiconductors, sensors, organic and
inorganic synthesis, superconductors, luminescence, glass, optical fibres. Beside the
main spectroscopic and electrical characterization techniques, advanced materials
analysis is achieved by means of AFM, STM, ESR, FIB, NMR, luminescence and electron
microscopy.
The research activities are also devoted to specific application fields like new materials
and techniques for energy, environment and cultural heritage.
Research is carried out within the framework of national and international projects,
leading to a great number of publications and patents.
The educational project aims at forming young professionals highly qualified in both
physics and chemistry, able to fit their knowledge to the contemporary requirements of
the related labour market. Milano-Bicocca University is in fact located in an area where
highly specialized high-tech companies are abundant, offering stimulating employment
opportunities in consolidated applications (elastomers, polymers, insulators,
semiconductors, ceramics) as well as in innovative materials (optical fibres, ionic
conductors, superconductors, organic and inorganic semiconductors, materials for non
linear optics, micro and opto-electronics, radiation detectors).
Degrees in Materials Science and in Chemical Science and Technology include a basic
degree (Laurea, three years), followed by a possible two-year specializing course
(Laurea Magistrale).
The three-years course of Optics and Optometry gives interesting professional
opportunities.
Finally, rich opportunities for post-lauream courses and research are offered by the
Doctorates in Materials Science, in Nanostructure and Nanotechnologies and in
Chemistry.

Organic and Hybrid Materials and Devices for
Photovoltaics, Artificial Photosynthesis and
Optoelectronics
ALESSANDRO ABBOTTO
ORGANIC AND HYBRID 3RD GENERATION PHOTOVOLTAICS
Our group studies organic and organometallic materials and devices for third
generation photovoltaics, including dye-sensitized solar cells (DSSC) and
organic/polymeric solar cells. Our work, in collaboration with national and
international partners, focuses on the synthesis of new photosensitizers, electrolytes,
hole conductors, and TiO2 films with tailored properties and optimized performances.
Our group is also involved in the design and synthesis of low-bandgap polymers and
molecules for optimal light harvesting and charge generation and transport in lowcost organic photovoltaic devices. Main design strategy is based on the use of donoracceptor (hetero) aromatic components for fine tuning of optical and electronic
properties. DSC and organic photovoltaic cells and modules are prepared and fully
characterized in the MIB-SOLAR Solar Energy Centre of the Department (ISO 7 clean
room), in collaboration with leading companies.
ARTIFICIAL PHOTOSYNTHESIS: CLEAND AND RENEWABLES SOLAR FUELS
This recent activity includes materials (photosensitizers, catalysts, etc.) and devices
(solar fuel generation cells) for artificial photosynthesis, namely production of
hydrogen and oxygen from water (water splitting) as clean and renewable solar
fuels. Focus is on the use of molecular and polymeric materials (including bioinspired dyes) as new efficient photosensitizers. Devices are investigated in the MIBSOLAR Solar Energy Centre of the Department.
ORGANIC MATERIALS FOR PHOTONICS AND OPTOELECTRONICS
Based on a multiyear experience on the design and synthesis of multipolar aromatic
and heteroaromatic chromophores we are currently investigating new molecular and
supramolecular organic and hybrid materials for multiphoton absorption, photonic
crystals, plasmonics, semiconducting polymers, and sensing of air and water
contaminants and explosives.
MAIN FACILITIES

Organic materials for photonics and
biophotonics
LUCA BEVERINA
HIGHLY-CONJUGATED ORGANIC MATERIALS FOR
PHOTOCONDUCTING, PHOTOVOLTAIC AND ELECTROCHROMIC
DEVICES
Organic -conjugated compounds have experienced over the last decades a
tremendous interest as versatile and highly performing active components in a large
variety of devices and applications including, among the others, OLEDs, OFETs, solar
cells, sensors, photodetectors, electrochromic devices, anti static coatings and
actuators. The vast majority of the above mentioned applications rely on the
peculiar nature of the charged states in organic semicondutors, namely: a strong
electron-phonon coupling and a major dependence of optical properties on the
doping process. We are currently exploring the ability of carefully designed organic
materials to: a) change colour upon multiple oxidation and reduction processes
(electrochromic devices); b) convert incident Vis-NIR light in electric power (solar
cells); c) Show efficient photoconductivity in NIR window (photodetectors). d)
Absorb light all over the visible spectrum and convert it to efficient and concentrated
NIR emission (luminescent solar concentrators).
LUMINESCENT SOLAR CONCENTRATORS
The potential of solar power is enormous, yet still largely unexploited because of the
high cost of efficient silicon-based solar cells. Moreover, the efficiency of standard
photovoltaic devices strongly depends on the light incidence angle and intensity.
Luminescent Solar Concentrators (LSCs) could provide cost reduction, while
ensuring operational capabilities under diffuse illumination conditions. LSCs are slabs
of transparent, high optical quality materials doped with luminescent molecules. The
molecules absorb sunlight and emit inside the slab. Since the refractive index of the
slab is higher than that of air, most of emitted light is guided to edges and there
collected by small area solar cells. .
CONJUGATED ORGANIC MATERIALS FOR OPTOELECTRONICS
The development of efficient structure-properties relationships in -conjugated
materials in particular is boosting the emerging field of the molecular electronics,
along with other interesting applications in research areas normally associated with
standard inorganic semiconductors such as high-speed telecommunication. We have
a strong experience in the synthesis and supramolecular ordering on highly
performing organic materials for electro-optic modulators.

Crystal growth and characterization of organic
and inorganic crystals: surface chemical reactions
and sorption processes
MASSIMO MORET
Growth and characterization of crystals is a mandatory step in many fields of science
and technology. Growth of crystals involves several chemical surface processes and
surface reactivity is a key point to understand and optimize crystal growth as well as
the interactions of crystals with natural or artificial environments.
Major areas of interest for inorganic systems are: crystal growth from solution
(synthesis of microporous coordination polymers with potential zeolite-like
behaviour) and study of sorption processes at the crystal/solution interface,
occurring in natural environments and in laboratory or industrial processes (e.g. the
setting of cements and plasters in the presence of organic additives).
In situ characterization of reacting crystal surfaces is mainly based on scanning
probe microscopy (SPM) with a dedicated fluid cell and a controlled environment. In
situ SPM allows recording of time evolution of surface topography and the study of
surface reaction kinetics.
Growth of organic semiconductor crystals (with solution, sublimation, physical vapour
transport, or organothermal methods) is complemented with ex-situ SPM, X-ray
diffraction, and hot stage optical microscopy. Theoretical modelling with Periodic Bond
Chain analysis and electron density partitioning of crystal space (Hirshfeld surfaces) is a
further step towards the detailed analysis of packing modes and intermolecular
interactions occurring during crystal growth.
Simulations of organic-organic heteroepitaxial layers are also performed by using
empirical force fields. Aim of these studies is analysing and predicting epitaxial
relationships between organic thin film deposits and organic crystal substrates.

Organic molecular systems for II order nonlinear materials, low energy emitters and
organic semiconductors
ANTONIO PAPAGNI
The current research interests are essentially focused on the development of organic
materials for applications in photonics and optoelectronics; the main topic is the
design and synthesis of semiconducting materials for alternative energy applications.
Organic solar cells (both bulk heterojunction solar cells and crystalline organic solar
cells) are the main target and the research activity involves two different kinds of
applications.
Bulk heterojunction solar cells (BHJSCs) are experiencing an impressive growth, both
for the continuous increase of photoconversion efficiency (PCE) and for the
increasing numbers of research groups and industrial players involved in this subject.
The still increasing values of PCE are the result of a careful design of the active
materials composing the core of BHJSC. The third generation of semiconducting
materials for BHJSC is give by internal donor-acceptor conjugated polymers. The
design of new electron-acceptors and the correct synthesis of donor-acceptor
polymers based on them are currently undertaken exploiting the know-how in the
field of fluorinated materials and also exploring alternative synthons. The fabrication
of solar cells and their analysis is carried out in collaboration with Italian and
European research centres and companies.
Crystalline organic solar cells are a less studied alternative to BHJSC, to overcome
some of their intrinsic limits. Crystalline organic materials, based on substituted
acenes, are a viable solution to get materials with higher mobilities and with a lower
density of defects. Acting on the dimension and electronic properties of the
peripheral substituents groups it is possible to tune the semiconducting properties,
absorption and emission energies and to act on crystal packing. For the fabrication of
crystalline organic solar cells Organic Beam Molecular Deposition (OMBD) is the most
suitable approach, allowing the controlled growth of crystalline organic multilayers
and nanostructures.
This activity is carried out with other researchers of this Department and with the
ISMAC centre of CNR.
A significant effort is also devoted to the analysis of degradation phenomena is
organic solar cells, to investigate the phenomena responsible for their thermal and
photodegradation and to develop strategies to increase their durability.

Synthesis and characterization of novel
polymeric nanostructures
ROBERTO SIMONUTTI
Nanostructured polymer materials have attracted growing interest due their
applicability in many different areas: from microelectronics to photonics, from
catalysis to water purification, from biomedical to military applications. Among many
different strategies used for preparing polymeric nanostructures, we focus our
research on self-organization of block copolymers and dispersion of inorganic
nanoparticles in polymer matrices.
NEW MATERIALS BASED ON BLOCK COPOLYMERS
Block copolymers are constituted by two or three different types of polymer chains
connected at the ends with a covalent bond. They display self-organization on the
nanometre scale modulated by the external environment. For example, the
interaction between block copolymer and solvent produces a diversity of self
assembled shapes, including vescicles, spheres, cylinders, that can be tuned by
concentration, solvent polarity, temperature and other external stimuli. The
morphology in the solid state can also be very complex and is finely tuned by the
conditions and the method of solid formation (melt cooling, casting from solvent).
Recently, by implementing advanced polymerization techniques like RAFT
(Reversible Addition-Fragmentation chain Transfer polymerization) we synthesized
several samples of highly controlled amphiphilic block copolymers. Our interest is
currently focused on innovative techniques for their characterization in liquid and
solid state, as well as the almost unexplored intermediate soft matter states: highly
concentrated solutions, gels and sponge-like materials.
NANOPARTICLE POLYMER NANOCOMPOSITES
The mixing of polymers and inorganic nanoparticles, like oxides, semiconductors
(usually defined as quantum dots) or noble metals, is opening pathways for
engineering flexible composites that exhibit advantageous electrical, optical, or
mechanical properties. In particular, the nanocomposite optical characteristics, as
the refractive index, absorption of UV light, birefringence or scattering properties,
can be modulated by carefully choosing the particle size and electronic structure of
the nanoparticle used for its preparation.
Our research is now directed to the use of oxide nanoparticles with all the
dimensions less than 100 nm.
A key point of the experimental activity is the
surface modification of the nanoparticles by a capping agent in order to increase the
stability of the colloidal dispersion.
Nanocomposite molecular structure, morphology and mechanical properties are
characterized by a comprehensive suite of advanced techniques, (among others:
FTIR, TGA, NMR, DLS, AFM). The measurement of optical properties (absorption,
transmission, angular scattering) of nanocomposite monolithic objects is done in
collaboration with the group of Prof. P. Di Trapani at the University of Insubria.
Another possible application of these nanocomposites is in the conservation of
cultural heritage, as protective layer that can protect the painting surface from UV
radiation, preserving the aesthetics.

Nanostructured materials and magic angle
spinning NMR
PIERO SOZZANI
The preparation and characterization of novel composite and nanocomposite
materials is the target of our research group. Reinforcing agents for polymers and
polymers as binders for reactive inorganic materials are mainly addressed. The effort
for optimizing the interfaces lead to the preparation of highly porous and shape
controlled silica-based materials and nanostructures which confine a second
component. In the latter case the nanocomposites show unusual mechanical and
optical properties. Electro-optical properties can be also modulated in the composite
and compared to the bulk. The link between structure and properties is provided by
a detailed characterization by magic angle spinning nuclear magnetic resonance
(MAS NMR), wide-line NMR and by other solid-state techniques (atomic force
microscopy, DSC and dynamic-mechanical analyzer). An NMR laboratory dedicated
to solids is available.
CURRENT RESEARCH PROJECTS
Composite materials based on ceramics and polymers and characterization of
heterogeneous interfaces (elastomeric materials reinforced with silica, in-situ
formation of silica by gelification in polymer matrices). Confinement of molecules
and macromolecules to cylindrical nano- and mesotubes (cross section of 0.5, 1 and
over 30 nm). Some matrices, showing extended interactive areas (>1200 m 2/g),
form supramolecular adducts endowed with unusual properties (liquid-crystalline
behaviour, anomalous glass-transition, conformational solitons propagating along
the polymer-chains even at very low temperature). The study of reactivity and
interactions among included species in molecular vessels is also addressed (gamma
ray initiated polymerization). Preparation of end-functionalized polymers to be
reactive onto heterogeneous materials. Crystal morphology, defects and
mesomorphysm of polymeric materials (ethylene-propylene copolymers). Diffusion
processes of gases into materials and exploitation of spin-active gases (129Xe)
diffusing into solids, for microphases determination and nanoporosity by NMR.

Theoretical modelling and ab-initio simulation
of material properties
MARCO BERNASCONI
PHASE CHANGE MATERIALS FOR DATA STORAGE
Phase change materials (Ge2Sb2Te5 and related telluride alloys) are attracting an
increasing interest worldwide for applications in optical disks (DVDs) and in a novel non
volatile electronic memory, the phase change memory cell. Both applications rely on a
fast (10-100 ns) and reversible transformation between the crystalline and amorphous
phases induced by heating. The two states of the memory can be discriminated thanks
to the large contrast in electronic conductivity and optical reflectivity between the two
phases.
On the basis of density functional molecular dynamics simulations, we investigate the
structural, dynamical and electronic properties of the amorphous and crystalline phases
of materials in this class aiming at establishing correlations between the composition of
the alloy and the electronic and optical functional properties exploited in the devices.
The models of amorphous phases (300-500 atoms) are generated by quenching from
the melt within ab-initio molecular dynamics simulations.
Large scale molecular dynamics simulations are also performed by means of interatomic
potentials generated by fitting a large DFT database with Neural Network methods.
The Neural Network potential allows simulating several thousand atoms for tens of ns
to study thermal transport at the nanoscale, the microscopic mechanisms responsible
for the fast crystallization and the properties of nanowires.
SURFACE PHONON AND TOPOLOGICAL INSULATORS
Some chalcogenide compounds of interest for phase change applications belong to the
class of topological insulators, i.e. they are bulk insulators with a non trivial topology of
the electronic bands which induces the formation of topologically protected metallic
electronic bands at the surface. On the basis of density functional perturbation theory,
we study the surface phonons and the electron-phonon interaction of Sb2Te3, Bi2Te3 and
the related semimetal elements Sb, Bi. The results are compared with measurements
from inelastic He atom scattering from experimental partner groups.

Optical spectroscopy and fabrication of
semiconductors and semiconductor
quantum structures
EMILIANO BONERA, EMANUELE GRILLI, MARIO GUZZI,
STEFANO SANGUINETTI
Our research is mainly devoted to the experimental study of the optical properties of
both group IV and group III-V semiconductors and quantum structures of interest for
micro- and opto-electronics. Most of our research is carried out in within the L-NESS
interuniversity Centre.
SiGe HETEROSTRUCTURES
SiGe alloys are of fundamental and applicative interest due to their structural, chemical
and electronic characteristics, for applications in microelectronics and photonics.
1. Using Raman and photoluminescence we study the correlations between growth conditions and
system properties. We analyse the effects of strain, composition and dimensionality on the
vibrational and electronic properties of the heterostructures.
2. The vibrational properties of SiGe nanostructures, mainly quantum dots, are currently under
study by Raman and micro-Raman measurements.
3. The electronic properties of Ge/SiGe multiple quantum wells are studied by transmission and
photoluminescence measurements in a wide temperature range.
4. Electron spin sensitive measurements on Ge/SiGe structures are performed; the
photoluminescence with light polarization control is studied.
QUANTUM STRUCTURES BASED ON III-V SEMICONDUCTORS
Amongst the
nanoscience advancements,
relevant place is taken by quantum
confinement effects that take place in semiconductor quantum dots (QDs). Like the
natural atoms QDs show discrete energy levels. Laser, infrared photodetectors, as well
as third generation photovoltaic cells show can be improved by the use of QDs in the
active layer. The study of QD-based devices has provided new ways for the
understanding of strongly correlated few electrons/excitons systems and their possible
applications, such as single-electron devices and single photon emitters for quantum
cryptography and computation.
1. We develop innovative growth procedures for the fabrication quantum nanostructures with adhoc designed electronic properties;
2. We study the nanostructure properties via spectroscopic measurements addressing electronic
structure and carrier relaxation mechanisms;
3. We study the transfer of the III-As QD devices on Si for integration with standard electronics.
FACILITIES
Spectroscopic apparatuses based on dispersive and FT spectrometers are used for
photoluminescence, photoluminescence excitation, transmission and Raman measurements in the
0.4 - 5.0 eV spectral range. Raman spectroscopy can be operated down to 5 cm-1. Working
temperatures: 2 K to 450 K. Sources: He-Ne, Ar, doubled-Ar, Ti-Sapphire, DPSS and Diode lasers,
incandescent and high pressure lamps. A low temperature (4 K – 300 K) micro-photoluminescence
and micro-Raman apparatus working in the 0.75 – 3.4 eV spectral range is available. Time resolved
photoluminescence and photoluminescence decay down to 10-8 s can be measured with DPSS-QS
lasers. Molecular-beam epitaxy for III-V semiconductors and AFM characterization.

Organic molecular semiconductors
ALESSANDRO BORGHESI, ADELE SASSELLA, SILVIA TAVAZZI
Thin film growth. Films of organic molecular semiconductors are grown by organic
molecular beam epitaxy (OMBE) under different conditions, such as pressure,
substrate type and temperature, absence or presence of external fields, for the
study of the growth process itself and of the intrinsic properties of the molecular
materials in the solid state and, in particular, in the form of thin layers, suitable for
device applications. Several molecules, such as oligothiophenes, oligocenes,
acridines, and porphyrines are studied. The OMBE growth process is monitored insitu by reflectance anisotropy spectroscopy (RAS), which also gives insight on the
evolution of the electronic properties of the films during growth. The morphology
and structural properties of the samples, closely related to the growth mode, are
then studied ex-situ, mainly by atomic force microscopy; finally, the optical and
transport properties of the molecular films are studied in comparison with the single
crystal properties.
Nanostructures. Films of different molecules are grown on high quality single
crystals of the same or similar molecular organic compounds, so as to reach homoand hetero-epitaxy, therefore preparing artificial structures with high quality
interfaces and controlled properties. Thin films are also stacked in multilayers on
different inorganic and organic substrates. The morphology and structure of each
layer, the interface quality, and the electronic states of the whole structure are
studied by scanning probe microscopies and by optical techniques.
Single crystals. Single crystals of the same molecular compounds are grown from
solution, from the vapour phase, and from floating drop, a technique developed in
order to obtain crystals of higher quality in terms of structure and surface control,
with shape and size suitable for their use as substrates for OMBE and for the
structural and optical studies.
Modelling. After the investigation of the single molecule characteristics from ab-initio
calculations, the results are used as microscopic ingredients for building the Frenkel
exciton Hamiltonian of single crystals of the same materials studied experimentally.
Thus, the dielectric tensor is calculated in order to simulate the crystal and thin film
optical spectra under different experimental configurations taking into consideration
optical anisotropy and directional dispersion.
FACILITIES
The OMBE apparatus consists of the introduction chamber, a second chamber for the
sample metallization, and the deposition chamber, where six sources are installed
for different compounds, a quartz microbalance controls the film thickness, and the
RAS apparatus is installed; a fourth chamber for in-situ optical characterization is
also available.
Optical spectroscopies, such as absorption, reflection,
photoluminescence and ellipsometry, are used for the study of thin films and
multilayers down to few K, also in comparison with the properties detected in-situ by
RAS. Atomic force microscopy is used for the morphology characterization of all the
samples and for the study of the film growth process.

Photophysics of molecular
semiconductors
SERGIO BROVELLI, FRANCO MEINARDI, RICCARDO TUBINO
1 Non-Coherent Photons Up-conversion. The generation of photons of higher energy with
respect to the excitation (up-conversion) through the non linear optical response of a
material is a phenomenon useful to reach spectral regions otherwise not accessible.
However, is appreciable only for coherent light sources delivering light intensity in the order
of MW/cm2. We are working on new routes to lower down to μW/cm2 the optical power
requirements for non-coherent light up-conversion based on harnessing energy through
bimolecular processes involving triplet-triplet annihilation indirectly excited via resonant
energy transfer in organic multi-component systems. The blue-shift of the excitation energy
has important applications in the field of solar energy photovoltaic conversion, as it allows
collecting photons in the low energy tail of solar spectrum which cannot be efficiently
converted. Moreover it can be exploited to develop novel blue and near UV light sources for
light emitting technologies like WOLED and colour displays.
2 One Dimensional Photonic Crystals DFB Lasers. The avant-garde development of smart
structures to provide optical feedback paves the way to the realization of novel laser
emitters. An interesting approach is the distributed feedback (DFB) based on photonic
crystals. In these systems a periodicity of the dielectric constant comparable to optical
wavelengths generates stopgaps, photonic band gaps and slow photons. Gain materials,
with which photonic crystals are doped, exhibit laser emission at wavelengths corresponding
to the edges of the photonic band gap. In this field, we are pursuing the fabrication and the
optical characterization of DFB lasers made with all-plastic and hybrid organic-inorganic one
dimensional photonic crystals, even on flexible substrates. Possible applications for this kind
of lasers are photonic and optoelectronic devices, such as optical switches, and sensors for a
wide variety of analytes.
3 Nanochannels and Artificial Antennae. Inclusion of luminescent conjugated molecules in
channel-forming compounds allows the formation novel hybrid materials. In this research
activity, artificial antennae are prepared by the inclusion of chromophores in a matrix with
nanometric channels, imposing to the chromophore specific organization and interaction with
the nanochanell surface. In particular, by using near infrared acceptor/emitters in these
spatially confined systems, interesting applications in the field of telecom and phototherapy
can be envisaged.
FACILITIES
Time Resolved Photoluminescence (PL). The main apparatus is based on a Ti:Sapphire laser
coupled with a streak camera.

Oxide nanostructures and silica-based
materials for optical technology
NORBERTO CHIODINI, ALBERTO PALEARI, ANNA VEDDA
Our research is focused on the physical properties of silica-based glass and glassceramics for applications in photonics and optolectronics. Bulk and film materials are
synthesized and investigated looking at the particular optical properties one can
obtain and control by doping with active ions and crystalline nano-phases. Doped
silica glass and glass-ceramics are technologically interesting for their signal
amplification properties in the telecom windows, nonlinear and light-emission
properties induced by dopants and crystalline nano-phases, and good optical
transmission and compatibility with existent glassy-silica based devices.
Fundamental aspects of the study regard the spectroscopy of rare earth ions, point
defects, and wide-energy-gap nanostructures in optical hosts. Synthesis techniques
have also been optimized to obtain good dispersion of active ions and crystalline
nano-clusters in glass-based materials.

Modeling and simulations of epitaxial
semiconductor depositions and
nanostructures
LEO MIGLIO, FRANCESCO MONTALENTI
Deposition of Ge (or, of SiGe alloys) on Si leads to a wealth of different phenomena,
mostly caused by the elastic energy unavoidably accumulated when trying to epitaxially
grow one material (Ge) on a substrate (Si) with a different lattice parameter. In our
group, we investigate such phenomena by formulating interpretative models based on
computer simulations.
For example, we are interested in understanding strain-release triggered formation,
stability, morphological evolution, and ordering of Ge nanostructures (islands), including
the effect of Si/Ge intermixing. A combination of different methods is needed to achieve
this goal. If atomistic Kinetic Monte Carlo and/or continuum models are needed to
describe growth kinetics, thermodynamic aspects can be tackled by a synergic use of
Density Functional Theory, providing surface energies, and classical molecular dynamics
simulations or elasticity theory (numerically solved by Finite Element Methods), used to
establish the volumetric elastic energy.
Particular attention is also dedicated to understanding the onset of plastic relaxation
(injection of misfit dislocations) both in flat SiGe/Si films and in SiGe 3D islands, and its
competition with elastic relaxation. To this goal, we developed a suitable methodology to
treat extended defects within a continuum approach.
Lately most of our attention has been focused on exploiting suitable patterning of a
Si(001) substrate to obtain ordered arrays of islands and/or to influence dislocation
nucleation, confining defects in desired positions. We have discovered that on a suitably
pit-patterned substrate, very peculiar processes take place, leading to an extrarelaxation (with respect to the flat substrate case) of nanoislands, with important
consequences also on the onset of plastic relaxation.
Our connection with experiments is extremely tight: we work in very close collaboration
with several international groups, and most of our representative works are jointly
published with them, offering at the same time both experimental evidence and
theoretical interpretation of a given phenomenon.

Chemical physics of surface
modification, gas sensing and
materials for photovoltaic application
MAURIZIO ACCIARRI, SIMONA BINETTI, DARIO NARDUCCI
SILICON SURFACE MODIFICATION AND GAS SENSING
Extended use of silicon in frameworks where its properties are insufficient is of
obvious relevance, due to the role this material plays and will play in
microelectronics and micromechanics. This research group has developed over the
years techniques capable of modifying silicon surface properties by grafting organic
moieties. The methods make use of solution chemistry reactions to bind organic
fragments through the formation of direct Si-C bonds. Such surfaces have been
therefore engineered, leading to the development of gas sensors that can be used as
sensing elements in gas sensor arrays. These devices have advantages over the
traditional, oxide-based gas sensors as they can be immediately integrated into
standard microelectronic boards. They also show enhanced stability and their
selectivity can be controlled and improved by an appropriate design of the organic
moiety, which acts as gas receptor.
SILICON FOR SOLAR CELL
The properties of defects in silicon have been studied for more than fifteen years
with substantial contributions to today’s knowledge of the mc-Si solar cells. Since
1990, the group has been involved in many European Renewable Energy Projectss.
Recently, under the realistic assumption that Si-wafer based PV modules will
dominate the market in the coming decade, we focused on the characterization of
low price and high quality solar grade silicon feedstock. In this frame our work is to
study the electrical properties and the recombination behaviour of extended defects
in a mc-Si ingot grown from metallurgical silicon These experiments allowed to
determine a limit for the concentrations of metallic and doping elements in the
feedstock with respect to solar cell efficiency.
INORGANIC SEMICONDUCTOR THIN FILM FOR PHOTOVOLTAIC
APPLICATION
Among thin-film technologies, advanced silicon
based
materials such as
nanocrystalline Si promise significant efficiency improvements to amorphous silicon
only if they are applied in a tandem junction structure. Thus, the properties of
nanocrystalline thin film have been studied using different techniques as the
prerequisite for the improvement of cell efficiency. Recently, the deposition and
characterization of CuInxGa(1-x)Se2 (CIGS) thin film has been started. CIGS is one of
the promising materials as an absorber of high efficiency thin solar cells. The growth
process developed used matches industrial requirements.

Theory and computations of low
dimensional materials
GIAN PAOLO BRIVIO
The main interest of the Group is to develop and interpret first-principle
investigations of electronic properties of novel low dimensional materials. The Group
is a core node partner of the European Theoretical Spectroscopy Facility (ETSF)
which comprises fourteen European Universities and Laboratories and whose aim is
the advance of computational spectroscopy. In our studies we make use of (and
contribute to) a plane-wave supercell code and of an embedding one, both within
density functional theory (DFT), and of localized basis set codes to work out
conductance properties through molecular junctions and interfaces. All these results
are of perspective applications in nano-electronic and photovoltaic devices.
CORE-LEVEL SPECTROSCOPY
The near edge x-ray absorption fine structure (NEXAFS) of aromatic molecules like
pentacene, a recurring ingredient in organic electronic devices, was computed by
first principles as a function of the photon polarization vector of a linearly polarized
X-ray beam. We highlighted and explained a splitting in energy for absorption peaks
relative to the various polarization directions. Such an effect can be used to
determine the orientation of the molecular plane in the condensed phase, as well as
of the molecules within that plane, as confirmed by experiments at the ELETTRA
synchrotron.
MAGNETIC NANOSTRUCTURES
The electronic and structural properties of a one-layer thick chromium oxide grown
on an iron substrate was characterized by first-principle simulations, together with
scanning tunneling microscopy and Auger experiments performed at Politecnico di
Milano. We have identified the magnetic state of the system to be
antiferromagnetically coupled with the substrate and highlighted the reasons beyond
the characteristic surface structures observed as a function of chromium coverage.
MOLECULAR CIRCUITS
We have computed the conductance of an hydrogen molecule embedded within
copper contacts under the application of an external bias, as it occurs in single
molecule break junction experiments. The dependence of the conduction channels
on the junction elongation and on molecular dissociation at the contact was
determined.

Energy storage materials.
Chemical synthesis, crystal structure,
theoretical models
Michele Catti
Inorganic materials of interest for ionic conductivity in lithium batteries and for
hydrogen storage (also in collaboration with Pirelli) are presently studied. The focus
is on relationships between structural properties, chemical composition, ionic
mobility and reactivity with hydrogen, in the frame of a more general study of phase
transformations in the solid state. Both experimental and computational methods
are employed.
EXPERIMENTAL
Chemical synthesis is performed by a variety of techniques, including hightemperature treatments in controlled atmosphere. A thorough crystallographic
characterization is then carried out by X-ray powder diffractometry. For the purpose
of fully determining the crystal structure of the phases obtained, neutron diffraction
data are often collected in several European centres (e.g., the ISIS facility at the
neutron spallation source of the Rutherford Appleton Laboratory, U.K.). The
reactions of hydrogen absorption and desorption are studied by a PCI (PressureComposition-Temperature) apparatus from the thermodynamic and the kinetic point
of view. Measurements of electrical (complex impedance spectroscopy) and
electrochemical properties are performed in the laboratory of Prof. C.M. Mari within a
collaboration.
COMPUTATIONAL
The theoretical investigations are based on quantum-mechanical periodic DFT
methods, with the aim of modelling the relative stability, the structural properties
and the ionic transport of crystalline phases.
RESULTS
Recently studied materials are the fast lithium ion conductors of the LLTO family
(Li0.3La0.567TiO3) with perovskite structure. Neutron diffraction data,
electrical
measurements and ab initio simulations allowed us to clarify the mechanism of Li +
ion diffusion in this material. A complex series of phase transformations, also
dependent on the thermal history, was revealed by Rietveld refinements from
neutron data. The Li+ ion disorder explains the two-dimensional high ionic mobility in
the (001) plane. By DFT calculations, it was possible to interpret the long-range
structural results on the basis of local models of the Li+ ion environment. The leastenergy ion mobility pathways are also under investigation, with the aim of
calculating the activation energy for the lithium transport process. The study of
other classes of lithium ion conductors has been now undertaken.
Mg-based alloys and borohydrides are being presently investigated for their
hydrogen storage properties, in collaboration with CORIMAV-Pirelli. The materials,
synthesized by the ball milling technique, show promising H-absorption behaviour
for particular compositions and crystal structures.

Materials for gas storage and energy
production: X-ray, neutron diffraction
and physico-chemical properties
ANGIOLINA COMOTTI
The research activity deals with the generation of frameworks containing one-, twoand three-dimensional confined spaces with uniform and precisely engineered
geometries to create new environments for storage of chemical entities. The study is
focused on new materials with nanoscale architectures for storage of important
gases such as methane and hydrogen considered as clean fuels, carbon dioxide that
is an intermediate product in the hydrogen production processes, and pollutant
vapours, especially benzene. The construction of stable and robust ionic, inorganic
and hybrid frameworks with 3D periodic motifs can increase separation, capture and
storage of small gases. These frameworks can arrange sites and receptors into
arrays for controlling and interacting with gas species. The advantages of the novel
materials will be compared with the conventional material properties for obtaining
the basis of patent applications.
The research activity is mainly devoted to physico-chemical methods for the
characterization of the porous structures and of the confined gases and vapours by
X-ray and neutron diffraction techniques. Advanced experiments using synchrotron
radiation and neutron sources will be performed at the European Facilities, especially
at ESRF (Grenoble) and Rutherford Laboratory (Chilton). The synchrotron X-ray
diffraction experiments enable the in-situ observations of the gas adsorption kinetics
whilst neutron diffraction experiments can detect the localization of stored gases.
The dynamics of gases and vapours in the confined state and the identification of
ionic and weak interactions will be studied in depth by inelastic and deep inelastic
neutron scattering.

Theory of oxide surfaces,
interfaces, and supported clusters
CRISTIANA DI VALENTIN, LIVIA GIORDANO, GIANFRANCO PACCHIONI
The understanding of the structure-properties relationship is of fundamental importance
for the design of new materials. In our group various models are employed to study the
electronic structure of inorganic and ceramic materials in combination with highly
accurate quantum-mechanical techniques. Particularly important is the role of theory in
the study of local sites or phenomena like atomic and molecular chemisorption, point
defects, impurities in solids, active sites or functional groups on surfaces, ultrathin films,
supported clusters, light-matter interactions, and for the interpretation of various
spectroscopies, IR and Raman, X-ray absorption and photoemission, EPR and NMR,
optical transitions, STM etc.
THIN OXIDE FILMS
Ultrathin oxide films grown on metal supports represent a new class of materials with
unprecedented properties. Our activity is directed towards the determination of the
electronic and structural properties of these systems, in particular work function
changes, presence of nanoholes or regular arrays of adsorption sites, reactive sites, etc.
SUPPORTED CLUSTERS
Metal nanoclusters as models of supported catalysts. We study the interaction and
stabilization of the metal clusters at specific sites of the support like oxygen vacancies
and other defects. We investigate the possible electronic modification of metal clusters
on ultrathin insulating films due to electron tunneling phenomena from the metal
support (charging, change in shape and reactivity, etc.). We also study the reactivity of
supported clusters in elementary steps of catalytic reactions.
OXIDE SURFACES
Structure and properties of oxide surfaces and of their interaction with adsorbed
molecules. Materials of technological interest in catalysis include very ionic solids like
MgO and CaO, more covalent oxides like SiO2, and intermediate cases like TiO2 and
Al2O3. The group is specialized in the study of chemisorption and reactivity, especially at
surface defects, and in the characterization of surface morphology.
DEFECTS AND DOPANTS IN OXIDES
Nature of point defects in oxide materials for photocatalysis, photoelectrochemistry,
microelectronics, fiber optics, , etc. in particular amorphous and crystalline TiO2, ZnO,
WO3, SiO2, alkaline earth oxides. The activity is directed toward the determination of
stability, structure, and spectral properties of intrinsic and extrinsic point defects
(vacancies, metal and non-metal dopants, codopants, hydroxyl groups, trapped
electrons, etc.) and their interplay through charge transfer processes. Particular
attention is devoted to the study of optical absorption for activation in the visible region
and of electron spin resonance spectra for identification of paramagnetic centres.

Electrochemical activities
CLAUDIO MARI, RICCARDO RUFFO
MATERIALS FOR ENERGY STORAGE AND PRODUCTION
This research line is devoted mainly to the investigation of electrode and electrolyte
materials for solid oxide fuel cells and for lithium ion batteries. Materials are
produced by our team or in collaboration with national and international research
groups. The electrical and electrochemical characterizations, carried out using
standard techniques such as impedance spectroscopy, d.c. Hebb Wagner
conductivity
measurement,
cyclic
voltammetry,
potential
spectroscopy,
galvanostatic cycling, are performed with the aim to investigate the correlation
among structural, morphological features and functional properties.
Materials for SOFC: the research activity is focused on the electrical characterization
of electrolyte materials alternative to YSZ and electrode materials compatible with
the new electrolyte. The results have shown the correlation between the dopant
amount and the ionic conductivity; moreover the conduction properties of several
possible cathode candidates have been determinate.
MATERIAL FOR GAS SENSORS
Solid state electrochemical as well as semiconductor gas sensors have been
investigated and realized. In particular, the former, either potentiometric or
amperometric, were investigated to determine the composition of CO/CO 2 or H2/H2O
gas mixtures and the concentration of CO or H2O or SO3 in air as well as Cl2 or O2
or CO2 in nitrogen and air.
The latter, nanostructured thin film of pure or noble metal doped semiconductors
prepared via sol gel or dip coating technique, were used as sensing elements to
determine low concentration of reducing gas (CO). The experimental measurements
pointed out the strong correlation among the electrical properties, the point defects,
the amount of doping level, and the morphology.
MATERIAL FOR ORGANIC OPTOELECTRONICS
Squaraine molecules, tiophene and pyrrole based monomers, and poly-tiophene
based polymers have been characterized respect to their electrochemical and
spectroelectrochemical properties in solution or in solid state (as thin film). Their
electronic properties, energy levels, and electro-optical characteristic have been
correlated to the chemical structure and to the film morphology. Recently, the redox
mechanism in conducting polymers was also investigated and the fundamental role
of anion intercalation pointed out.

Chemistry of inorganic and
organometallic materials
FRANCA MORAZZONI, ROBERTO SCOTTI
The research activity concerns with the synthesis, the spectromagnetic
characterization and the functional study of metal oxide based materials. At the
present time the active research lines are:
NANOSTRUCTURED SEMICONDUCTOR OXIDES FOR SENSOR DEVICES
Nanostructured semiconductor metal oxides (SnO2, TiO2, WO3), pure and doped with
transition metals, are prepared by soft chemistry techniques as base materials for
gas (CO, O2, NOx, NH3) sensor devices. In particular the research focuses on the
preparation of oxide films having the macroporous inverted opal architecture built
by nanocrystalline bridges and junctions around regular arrangement of air spheres.
High surface area and controlled porosity of such structures lead to improved
sensing performances over traditional oxide devices. Suitable spectroscopic and
magnetic techniques are used to recognise centres and defects responsible for the
electrical response and to suggest new ways for improving the efficiency.
NANOSTRUCTURED PHOTOCATALYTIC MATERIALS
Nanosized and mesoporous TiO2 with controlled morphology, particle size and
shape, crystalline phase composition, are synthesized by means of different
preparation methods (hydrothermal, surfactant assisted sol-gel) and used as
catalysts in the photocatalytic oxidative detoxification of water and air. The same
catalysts are immobilized on supports or used as glass coating to induce selfcleaning properties.
Kinetic and mechanistic investigations are performed in order to find correlations
between the photocatalytic activity and the phase composition, morphology and
structure of the oxide. In particular Electron Paramagnetic Resonance investigations
allow to study at molecular level the species involved in the photocatalitic processes:
electron and hole trapping centres (Ti3+, O- and O2-) in UV irradiated TiO2 and shortlived OH- radicals.
FACILITIES

compounds, thermal treatments under controlled atmosphere, preparation of
samples for spectroscopic measurements, high pressure treatments and reactions.

Dating and characterization of
ancient materials. Materials science
and cultural heritage
ANNA GALLI, MARCO MARTINI, EMANUELA SIBILIA
Since 1980 our activity has been mainly focussed on the application of scientific techniques to
archaeology, geology and cultural heritage, in particular in the field of absolute dating and
characterisation of archaeological materials. For what concerns the dating techniques,
thermoluminescence (TL) and optically stimulated luminescence (OSL) are used to determine the
event of ceramics firing and sediment deposition respectively. Other available techniques are
dendrochronology (dating of wood) and radiocarbon (preparation of samples for Accelerator Mass
Spectrometry, AMS, to evaluate the concentration of 14C atoms in organic remains).
The laboratory is member of the CUDaM (Centro Universitario Datazioni Università di Milano
Bicocca, http://cudam.mater.uninib.it) , and of the CRESM (Cultural Resources Management
Centre, http://cresm.unimib.it).
The main application is to ceramics from archaeological excavations, and bricks from historical
buildings. Beyond ceramics, good results are reached with hearths, kilns, flints and clay-cores of
bronzes. Our activity has been recently oriented to the study of non ceramic materials
(archaeological glasses, metallurgical slags, mortars) and to geological applications
(luminescence dating of eolic and marine sediments, volcanic tufa, palaeosoils).
Main activities:
-Fundamental study of the low temperature TL peak in quartz and of the Pre-dose effect
-Study of the optical properties of mosaic glasses
-Study of charge transfer phenomena in quartz and feldspars luminescence.
-Studies of new procedures for the extraction of collagen from modern and archaeological bones
for 14C dating
-Studies of new procedures for identifying and selecting the anthropogenic calcite from the
geogenic one in archaeological mortars; TL and OSL dating of mortars.
-Surface dating
-Study and characterisation of natural dosimetric materials for accident dosimetry

Scaling Hetero-Epitaxy from Layers to Three-Dimensional Crystals.

Chrastina, G. Idella, E. Muller, P. Niedermann, and Leo Miglio. Science 335,

Quantum structures made from epitaxial semiconductor layers have
revolutionized our understanding of low-dimensional systems and are used
for ultrafast transistors, semiconductor lasers, and detectors. Strain
induced by different lattice parameters and thermal properties offers
additional degrees of freedom for tailoring materials, but often at the
expense of dislocation generation, wafer bowing, and cracks. We
eliminated these drawbacks by fast, low-temperature epitaxial growth of
Ge and SiGe crystals onto micrometer-scale tall pillars etched into Si(001)
substrates. Faceted crystals were shown to be strain- and defect-free by xray diffraction, electron microscopy, and defect etching. They formed
space-filling arrays up to tens of micrometers in height by a mechanism of
self-limited lateral growth. The mechanism is explained by reduced surface
diffusion and flux shielding by nearest-neighbour crystals.

Traditionally, magnetic storage materials make use
of magnetic fields to address individual storage
elements. Using magnetic circular dichroism we
show
that
copper
doped
semiconductor
nanocrystals represent a new class of diluted
magnetic semiconductors. Furthermore, our results
demonstrate that these clusters also exhibit a
pronounced
and
persistent
photo-induced
magnetization, suggesting the feasibility of new
approaches to magnetic storage in which
magnetically encoded information is manipulated
not by magnetic fields but rather by using much
more flexible optical illumination.

Donaldson, Materials Today 15, 139 (2012).
“Considerable
research
time
has
been
dedicated to designing light-emitting diode
(LED) devices that can be applied in biomedical
diagnostics and medical devices; the holy grail
has been to produce them cheaply and so that
they can be integrated into existing technologies. Now a new study […] has pushed back the
boundaries of nanocrystal science by producing a new glass-based, inorganic material that can
emit light in the ultraviolet spectrum and be integrated onto silicon chips common in most
electronic technologies. The team […] developed a process for creating such nanocrystal LEDs
[…] through a wet-chemistry approach […]. The devices have both chemical inertness and the
mechanical stability of glass, as well as having electric conductivity and electroluminescence,
allowing them to be utilized in difficult environments […].”

We

can
be
qualitatively changed from a) a perfectly
colourless and highly transmitting one, b) an intense-blue collared one, and c) a state
characterized by strong opacity, without a well-defined colour and, as such, suitable for
applications such as intelligent windows, electrochromic lenses for sun glasses and electrochromic
windows for automobiles.

Dipeptide Crystals as Polymerization Nanoreactors. Angew.

Issue).
The potential of porous materials, both as fully-organic covalent
frameworks [1] and molecular crystals of biological origin, [2] has
been exploited for solid state polymerizations in the confining
cavities. After a sophisticated series of transformations, which mimic
enzyme activity, hierarchical ranks of order could be transferred to
the native polymer, controlling properties such as stereoregularity,
chain alignment and replica of crystal morphology. The
extraordinary surface areas (> 5000 m2/g) and the robustness of
porous architecture enabled the formation of polyacrylonitrile (PAN) and its thermal
transformation into conductive and semi-conductive nanofibers tightly interpenetrated with the
porous matrix. By an innovative procedure, PAN was also synthesized within the nanochannels of
dipeptide crystals to yield an isotactic polymer. Upon heating, the sacrificial crystal sublimed
away, while the polymer chains transformed into rigid ladder structures which retained the order
of the pristine crystal scaffold.

Laboratory of Scanning Electron Microscopy and Microanalysis
www.mater.unimib.it/utenti/sem/SEMWEB/
The Scanning Electron Microscope (SEM) allows to obtain three-dimensional images at high
resolution (~ 5 nm) by scanning an electron beam in a small area of the test sample. All the
effects that are produced in the point of impact of the beam can be used, with appropriate
detectors, to produce a contrast, and then the image. Furthermore, the analysis of the
producedX-rays allows to perform compositional analysis with high spatial resolution
(microanalysis). The sample to be examined must be conductive.
In case the sample is not conductive it is possible to deposit a thin gold film in order to make
possible the vision. The microscope available in our laboratory allows the viewing of nonconductive samples even in the absence the gold film. Our SEM offers the opportunity to work
in conditions of variable pressure of argon using an exclusive detector for low vacuum LVSTD.

FIB/SEM BOMBAY LABORATORY. SOFT AND BIOLOGICAL MATERIALS
MICROMANIPULATION AND MICROSCOPY
Following a joint application of the Department of Materials Science and Department of
Physics, a FEI Quanta 3-D DualBeam system was installed at Milano-Bicocca University in
the mid of 2006.
This important system (hosted by the Center of Excellence
Plasma Prometeo) is devoted to studies on soft materials
and biological specimens, that hopefully could invade the
field of nanomedicine. Actually nanotechnology has led to a
remarkable convergence of disparate fields including
biology, applied physics, optics, computational analysis,
modeling, and materials science.
The DualBeam system combines a Scanning Electron Microscope (SEM) with a Focused Ion
Beam (FIB). The SEM is based on a tungsten electron column, able to operate as a
conventional, high vacuum SEM or as an Environmental SEM,
which allows working pressures up to 3000 Pa during electron
microscopy by means of special gaseous detectors.
The Focused ion beam (FIB) is a tool that performs basically
three functions: ion imaging (from secondary electrons or
ions), milling (precision down to 10 nm) and deposition (with
the insertion of a small needle delivering special gases).
The FIB/SEM Quanta 3-D provides further options, e.g.:
• electron imaging of the sample during navigation without
erosion or gallium implantation produced by the ion beam;
• on-line operations in which the SEM is used ‘to film’ the cross-section face while FIB mills
normal to the surface;
• the electron imaging of charging specimen in absence of metallization can take place before
or after the FIB operations in the same chamber;
• Charge neutralization of the sample with electron beam during FIB milling;
• Two gas injector systems (GIS) for selective carbon milling (SCM) and Pt deposition;
• Alternative use of the electron beam induce deposition instead of the ion beam induced
deposition in order to deposit films and growth nanostructures in a milder way.

DELTATI RESEARCH
In 2011 the University of Milano-Bicocca and ERG SpA gave birth to DeltaTi Research, a
consortium entirely funded by ERG and aimed at the development of nanostructured siliconbased thermoelectric generators. Thermoelectric conversion, although known since 1821, has
found limited industrial exploitations because of the relatively low conversion yield it enables and
of the high material costs. In spite of the technological limitations, recovering low-enthalpy heat
would disclose unpaired opportunities to generate electric power out of thermal waste available
both at civil and industrial facilities – further to improve the efficiency of thermal engines.
Based upon a new technological approach developed at the Department of Materials Science and
protected by seven international patents, silicon nanostructures might be considered for
industrial-scale production of low-cost, high-efficiency generators that will be used both for bulk
electric generation and for power microgeneration.
The Consortium R&D activity currently involves, along with the University of Milano-Bicocca as
research leader, two CNR institutes, the Universities of Modena, Naples, and Vienna, the
Fondazione Bruno Kessler, the Demokritos Research Center, and Altran as a technological
consultant.
PILEGROWTH TECH S.R.L.
The company, established in September 2012 and spin-off of the University of Milano Bicocca
from the very beginning, originates from one technological breakthrough for semiconductor
integration in silicon obtained by Prof. Leo Miglio (CEO) and Prof. Hans von Känel (ETH Zürich,
CTO), within the L-NESS inter-university center. It aims at developing, licensing, or selling
innovative technologies manufacturing semiconductor structures and devices, with specific
application to thick-film systems, such as high-efficiency photovoltaic cells, imaging detectors and
power electronics devices. The company received Seed Money financing from Italian venture
capital investors and one industrial partner. The targets of the first year are to provide one
demonstrator of Ge/GaAs-, or Ge/GaAs/InGaP-based PV cells for satellite applications, and the
proof of concept that SiC-based power devices can be integrated in silicon. PileGrowth Tech is
characterized by a strong link to international semiconductor laboratories, both in academia and
in the industry. Actually, contracts with the University of Milano Bicocca, Politecnico of Milano,
the IMM-CNR Institutes of Catania and Bologna, PV cell manufacturers, such as CESI in Milano
and ENE in Brussels, and ETC srl, SiC process developer in Catania, are already running. A strong
scientific collaborations with Swiss federal institutions, such as ETH Zürich, CSEM SA (Swiss
Center for Electronics and Micromachining) Neuchatel, and EMPA (Federal Institute of Materials
Certification) are particularly active, within a collaboration for developing a new Ge-based X-ray
imaging detector, integrated on a Si CMOS chip.

Corso di Laurea in Scienza dei Materiali:
sbocchi occupazionali (in italian)
Il Corso di Laurea ha come obiettivo la formazione di una figura professionale con buone
conoscenze in campo fisico, chimico e matematico, in grado di applicare tali competenze in un
ambito multidisciplinare.
Grazie a questo e alla ricchezza sul territorio di industrie che si dedicano allo sviluppo sia di
materiali maturi (elastomeri, polimeri, isolanti, semiconduttori, leghe, ceramici), sia di
materiali innovativi (fibre ottiche, conduttori ionici, superconduttori, materiali elettro e fotocromici e per ottica non lineare), gli studenti di Scienza dei Materiali ricevono in breve tempo,
dopo la laurea, diverse proposte occupazionali anche a tempo indeterminato.
I laureati in Scienza dei Materiali contribuiscono alla crescita di questi settori sia nello
sviluppo di nuovi materiali sia nell'intero processo di produzione, dalla gestione d'impianto al
controllo di qualità.
Oltre al lavoro in industria si aprono per gli Scienziati dei Materiali la carriera di libero
professionista (certificazione, consulenza, etc.) e quella di ricercatore, il cui primo passo sono
i Corsi di Dottorato di Ricerca in Italia e all’estero.
