Abstract:

This review paper describes optical and electrical properties of Chalcogenide glasses. By the virtue of these properties, these glasses have been incorporated in various semi-conducting electronic devices like optical memory, thin-film transistors and the scope of research and development is still extant. The electrical properties discussion includes trends and theories associated with AC/DC conductivities, defect states, dielectric losses and thermally stimulated currents (TSC). In addition, various theories explaining localized states and band gap like Poole Frenkel, Space Charge Limited Current (SCLC), hopping conduction etc. have been introduced. The optical properties summarize methods of measurement of optical band gaps, optical constants and photoconductivity variations in different glasses.
