Abstract : Under contract N00014-90-C-2020, SFA provided research support to the Naval Research Laboratory Electronic Materials Branch by conducting investigations on novel materials. These investigations ranged from using various techniques to characterize the optical, electronic, and structural properties of this semiconductor films to setting up a micro-Raman and microphotoluminescence laboratory to study microcrystalline films. The materials studied include heavy metal fluoride glasses, chalcogenide glasses, silicon carbide, diamond (chemical vapor deposition films, high-pressure, high- temperature synthetic and natural), and aluminum nitrides. These materials were investigated by such optical techniques as Raman scattering (RS), photoluminescence (PL), photoluminescence excitation, absorption, reflectivity, electron spin resonance (ESR), photo-induced ESR, optically detected magnetic response (ODMR), and Hall measurement.
