摘要

The main objective of this project was to characterize the linear and non-linear infrared optical properties of technically important semiconductors in varied sample geometries, such as bulk, near a surface and in film geometry. Surface polaritons and guided-wave polaritons in GaP and GaSe were studied by Raman scattering spectroscopy. Resonance Raman effects were investigated at the indirect gap of Ga P. The structure of amorphous Se-Ge glass was determined by Raman scattering. A double grating spectrometer and a Fabry-Perot interferometer were interfaced to an LSI-II minicomputer using a CAMAC system. Keywords: Infrared radiation; Infrared phenomena. (kt)
