Influence of post-deposition heat treatment on optical properties derived from UV-vis of cadmium telluride (CdTe) thin films deposited on amorphous substrate

- Annealing-induced change in optical parameters of CdTe film was derived from UV-vis study.
- Optical constants of the films were evaluated using Swanepoel method.
- Dispersion energy data obeyed the single oscillator of the Wemple−Didomenico model.
- Cd deficiency of the film confirmed the p-type conductive nature.
