Introduction to crystalline properties of semiconductors - Energy band theory - Conduction in semiconductors (electrons and holes, conductivity, donor and acceptor impurities, Fermi level, diffusion , continuity equation) - Semiconductor diode (theory of the P-N junction, the volt-current characteristics, junction potential, forward and reverse bias, diffusion capacitance) - Diode circuit applications (rectifier circuits, clipping circuits) - Zener diode.
