SOLID STATE ELECTRONICS

Solution of Schrödinger equation for periodic potential (zonal model, Bloch’s wave functions, dispersion equation, equienergy surfaces in k-space). Electron dynamics in crystals (motion of electrons, holes, effective mass, energy states density). Localized electron states (impurities, surface, polaron and exciton states). Electron transport processes (Boltzmann kinetic equation, Fermi quasilevel, concentration, mobility and conductivity of electrons and holes, drift and diffusion, Einstein’s relationship; galavanomagnetic, thermoelectric and thermomagnetic effects, Hall effect). Recombination (lifetime, surface recombination). Thermoelectronic emission. Metal-semiconductor and semiconductor-semiconductor junctions (heterojunctions, PN junction; injection, capacitance, current flow, breakdown).
