Summary of Research Program a Chemical and Physical Properties of Surfaces and Interfaces -- The LRSM has a broadly based program of research on chemical and physical phenomena which occur at the surface of materials or at the interface between two materials. The long range goal of this program is to achieve the kind of deep understanding of such phenomena at the microscopic level which we now have about many important phenomena in bulk materials. b IV-VI Semiconductor Films and Surfaces -- The purpose of this work is to explore and exploit several phenomena in semiconductors, especially lead chalcogenides. Emphasis is placed on possible device applications. c Intercalated Graphite Compounds -- The research program in the LRSM on intercalated graphite compounds has three ultimate objectives a to synthesize graphite intercalation compounds with room temperature conductivities comparable to or even greater than that of copper b to obtain sufficient understanding of the effects of intercalation on the electronic structure to guide the synthesis and c to develop high-strength composite materials which will allow the practical realization of highly conducting intercalation compounds.
