Course: Physics of Nanostructures

Department/Abbreviation: SLO/BFN

Year: 2020

Guarantee: 'doc. Mgr. Jan Soubusta, Ph.D.'

Annotation: Brief introduction to solid state physics. Starting point is the description of the geometry of different crystals. Regular arrangement permits to use energy band model and elementary excitations as phonons, plazmons or excitons.

Course review:
- Spatial arrangement in mesoscopic systems, the most frequent crystal structure (SC, FCC, BCC, HCP). - Reciprocal lattice, Brillouin zone, Bragg law of diffraction, experimental diffraction methods, structural factors, Fourier analysis of the base. - Crystal bonding, ionic crystals, covalent crystals, metals, crystals of inert gases. - Lattice vibrations, acoustical, optical phonons, dispersion relations. Thermal properties Einstein model, Debye model of heat capacities, thermal conductivity. - Metals, Fermi gas of free electrons, thermal and electrical properties, Ohm law, Hall coefficient, cyclotron frequency. - Fermi surfaces in metals, nearly free electron approximation, tight binding method. - Energy bands, Bloch theorem, Bloch functions, central equation, Kronig-Penney model. - Semiconductors, dispersion relations of real materials (Si, Ge, GaAs). Thermoelectric phenomena. - Plasmons, collective excitation, definition of plasma, plasma frequency, dispersion law for electromagnetic waves, plasmons, polaritons - Optical processes, excitons.
