Influence of heat treatment on the structural, optical and electrical properties of Cd20Sn10Se70 thin films

The effect of annealing temperature (Ta) on the structural, optical, and electrical properties of thermally evaporated Cd20Sn10Se70 thin films has been investigated. Differential Thermal Analysis (DTA) was used to determine the glass transition temperature (Tg) of the prepared alloy. X-ray diffraction studies showed that the as-deposited film and the films that were annealed at Ta
