Kommentar
This course will cover the following topics:
Crystal structure: lattice and Basis, 2D and 3D lattice types, index systems for lattice planes
Wave diffraction and reciprocal lattice: Bragg Law, Fourier analysis, Laue condition, Brillouin zones
Crystal Binding: van der Waals interaction, Lennard-Jones potential, Latiice Constants, Cohesive Energy
Phonons: Planck distribution, DOS, Debye law, Einstein model Free electron Fermi gas: energy levels, Fermi-Dirak distribution, free electron gas
Energy bands and semiconductors: nearly-free electron model, band gap, Bloch functions
Fermi surfaces and metals: tight Binding, cohesive Energy, pseudopotential method
Point defects and diffusion: vacancy, interstitial, Frenkel, Schottky, F-centre
Surface and interface properties: electronic and atomic structure, Work function, relaxation and reconstruction
Imaging techniques for surfaces and nanostructures: electron microscopy, scanning tuneling microscopy, atomic force microscopy
