Abstract:

The dynamic structure of liquids and disordered solids is investigated by Rayleigh, Brilloin and Raman light scattering, by nuclear magnetic resonance and by infrared absorption. Simple liquids, liquid crystals, polymers, glasses, organic semiconductor and hydrogen in metals are the objects of investigation. The properties of light emitting and laser diodes of the semiconductors GaAsP, InGaAs, and InGaP are investigated to improve and extend their behavior. Impurities and imperfections in silicon which affect the properties of solid state devices are investigated for the purpose of controlling and improving device performance.
