Amorphous Semiconductors

Abstract

This work has been based entirely on studies of bulk semiconducting alloy glasses mainly from Ge, Te, As, Se combinations. Known amounts of the desired constitutients (five 9's pure) are crushed, then weighed out in an inert gas atmosphere. They are then placed in a quartz ampoule, sealed off under fore-pump vacuum, and placed in a rocking tube furnace. Heating cycles depend on the material used but generally involved temperatures near 800C and periods of approximately one day. Samples were dropped from the furnace to an air or water quench. Once the glass ingot is removed from the ampoule it is cut into suitable lengths. The report provides details of work on sample preparation and other experimental procedures; together with results on equation-of-state, the glass-transition phenomenon, and dc and ac conductivity.
