Abstract:

The effort has been concentrated on investigations of the energy bands in semiconductors by optical methods dealing with the lead salt compounds Pbs, PbSe, and PbTe, as well as certain intermetallic semiconductors. This work also includes measurements of the reflectivity of intermetallic semiconductors. Investigations of the composition properties of lead telluride have resulted in a better understanding of the phase diagrams of lead telluride. We have continued work on surface effects and transport phenomena, and on the study of recombination lifetimes. The magnetic behavior of rare earth magnetic alloys has been examined. The effect of Zeners double exchange phenomenon has been obtained in certain manganese compounds. We have carried out theoretical work on crystal and magnetic anisotropy and how it relates to the intensity of magnetization and the Curie temperature. The physical properties of materials have been studied, in particular the properties of intermetallic metals, metal oxide whiskers, and the structure of fuzed silica.
