THERMALLY INDUCED STRUCTURAL DEFECTS IN SPRAYED γ-In_2Se_3 CHALCOGENIDE GLASSES: EFFECTS ON PROPERTIES

摘要

Binary and ternary chalcogenide glasses belonging to the chalcogens, S, Se and Te in the form of sulfides, selenides and tellurides are attractive materials for applications such as photo-conducting cells, photovoltaic cells, and other opto-electronic devices. Indium selenide shows suitable properties for photovoltaic and photochemical application because of an absorption coefficient associated with an energy gap in the range of solar energy conversion. Recently Lee et al. proposed a γ-In_2Se_3 phase-change memory device with rewritable capabilities.
