3375 Structure and Electrical Properties of Materials

- Introduction to quantum mechanics. Schrödinger's equation. Quantum mechanical tunneling and applications. - The creation of energy zones/bands, the classification of materials according to their energy gap. - Crystal structures. Ideal, real. Crystal defects. Diamond crystal structure. The effects of crystal defects on the potential energy graphs (energy gap levels, surface energy levels). - Distribution functions. Fermi-Dirac statistics. Concentration, mobility of charge carriers, scattering, and effective mass of electrons-holes. Conductivity in semiconductors. - Classical and quantum mechanical transport phenomena: Drift - diffusion and tunneling phenomena – thermionic emission. - Interaction of light and semiconductors. Photon absorption and recombination. Radiant and non-radiant recombination (between Auger-type bands, and deep electronic states). - The continuity equation. - Semiconductor metal contact (Schottky diode, ohmic contacts). p-n diode
