The student will acquire the basics required to deal with issues related to the physical and chemical properties of nanoscale systems and highly organized. Final goal will be to facilitate the student's placement in both a modern industrial and technology environment and research and development.

-The development of new advanced techniques of synthesis and assembly, makes it possible to obtain low-dimensionality ' (e.g. thin films, nano-wires, nanoclusters or nanoparticles) or "supramolecular systems" whose physical and chemical properties are different from those of molecules from those of solid-state materials and make them extremely useful for applications in the field of new technologies. Will be examined the physical and chemical properties of certain classes of nanomaterials, highlighting in particular their variation as a function of dimensionality and the size of the material. Particular attention will have the theoretical analysis of the main characteristics of nano systems and their relationship to the property of extended systems and of molecular systems.
-In this course, after a brief introduction to nanotechnology, will be considered examples of Nanosystems (both existing in nature and obtained in the laboratory), the mechanism of operation will be investigated at the microscopic level and theoretical and will be investigated methods for their chemical and physical characterization.
-Theoretical and experimental methods of characterisation of the physical and chemical properties of metals and semiconductors and nano structured, with particular attention to the problem of quantum confinement.
-Optoelectronic properties of supramolecular aggregates and their theoretical interpretation.
-Hot Topic: presentation of current interest (i.e. Graphene).
-Will also be presented and discussed the various stages of planning and construction of devices, based on nano-structured systems, having certain properties of technological interest.
-The course includes as an integral part laboratory exercises (24 h), whose frequency is compulsory. The exercises consist of two phases, an experimental and a computational one: in the first the student will apply computational techniques to the study of electronic properties of semiconductor systems with reduced dimensionality. The experimental phase involves the implementation of a photovoltaic device based on nanoparticles.
The course includes frontal lectures (32 h) and practical exercises in the laboratory and computer room (24 h).
