Fundamentals of thermodynamics, quantum mechanics and statistics.
Oral examination. Students should discuss a free chosen topic, and should answer to questions related to the program and to the laboratory report.
Objectives of the course are the understanding of the problems related to the physico-chemical properties of systems on the nanometer scale or highly organized (supramolecular aggregates) systems.
Relationship between size and chemical-physical properties of solids (2 hours)
Relevance of surfaces, and their description, in nanometric systems (2 hours)
Surface area measurement, Langmuir and BET isotherms (2 hours)
Bloch states for crystalline systems. Tight Binding approach to the electronic structure of solids (4 hours)
Band structure of systems in one, two and three dimensions, quantum dots (4 hours)
Conductors, semiconductors and insulators. Outline of superconductivity (2 hours)
Quantum size effects in semiconductors (Brus approach) and metals (Surface Plasmons) (2 hours)
Photophysical and photochemical processes in molecular systems, (2 hours)
Quantum yield and relaxation kinetics of excited states (2 hours)
Molecular aggregates, supramolecular organization and electronic states (2 hours)
Molecular excitonic systems, J and H type aggregates (2 hours)
FRET processes, Foerster approach. (4 hours)
Presentation of a topic of current interest (e.g. CNT or graphene) (2 hours)
The laboratory part (mandatory), involves the assembly of a photovoltaic cell based on nanostructured semiconductors and organic dyes (12 hours). Students will also attend a virtual laboratory at computers (12 hours).
