Course Description
Chemical bonds and crystal structure of solids, direct and reciprocal lattice, study of crystal structure, examples and applications. Molecular vibrations and vibratory spectroscopy techniques. Lattice oscillations in one and three dimensions, phonons and dispersion terms, phononic state density and experimental study techniques (inelastic scattering of neutrons and X-rays). Thermal properties of lattice, specific heat, non-harmonious interactions and thermal expansion, thermal conductivity of solids.
Electronic structure of typical semiconductors, carrier density, impurities, scattering mechanisms & conductivity. Semiconductor alloys, Vegard’s law & band-gap engineering. Band offset in heterocontacts and Anderson’s rule. Effect of strain on films. Doping modulation & quantum wells. Modification of the electronic structure due to quantum limitation. Current trends in Wide Gap Semiconductors (WBG) and Ultra-WBG.
