Research on the Properties of Amorphous Semiconductors at Elevated Temperatures is organized into three broad topics 1 Glassy alloy studies, including both survey studies and detailed composition-property studies in a few selected systems. Much emphasis in these studies has been placed on the correlation of thermal, electrical, and optical data in understanding chemical bonding and the associated band level structure in amorphous chalcogenide alloy systems 2 The role of deposition techniques in controlling thin film composition, structure and properties with special emphasis on the roles of argon entrapment and substrate bias during the r.f. sputter deposition of amorphous chalcogenide alloys 3 Studies of controlled changes in conductivity, refractive index, or absorption, produced electrically, optically or thermally in Ovonic threshold and memory alloys.
