Comments
This course will cover the following topics:
Crystal structure: symmetry, lattice and Basis, 2D and 3D lattice types, index systems for lattice planes, close packing structures, typical metal or semiconductor or ionic structures
Wave diffraction and reciprocal lattice: Bragg Law, Fourier analysis, Laue condition, Brillouin zones
Crystal Binding: van der Waals interaction, Lennard-Jones potential, metallic bonds, ionic bonds, Lattice energy, Cohesive Energy
Electrical conductivity in metals: Drude model, free electron Fermi gas (energy levels, Fermi-Dirac distribution), energy bands, Bloch function
Semiconductors: band structure, nearly-free electron model, holes, effective mass, doping
Phonons: Planck distribution, DOS, Debye law, Einstein model (if time permits) Free electron Fermi gas: energy levels, Fermi-Dirak distribution, free electron gas
Point defects and diffusion: vacancy, interstitial, Frenkel, Schottky, F-centre
Surface and interface properties: electronic and atomic structure, Work function, relaxation and reconstruction
Techniques for surfaces and nanostructures analysis: X-ray photoelectron spectroscopy, scanning tuneling microscopy, atomic force microscopy
