Structural and Optical Properties of Thermally Evaporated CdTe Film

Abstract:

Abstract. Cadmium Telluride (CdTe) films were thermally evaporated on to glass substrates at room temperature. By varying the amount of source material, thin films of thickness ranging from 90 nm – 635 nm have been prepared. Film of thickness 200 nm was annealed to 400°C for different durations of time and also subjected to alternate heating - cooling cycle. X-ray diffraction study was carried out to study the effect of film thickness, annealing duration and alternate heating-cooling cycle on the structural properties of the films. The transmittance spectra recorded using a UV-Vis-NIR spectrophotometer was used to study the change in optical properties of the films with respect to film thickness, annealing duration and alternate heating-cooling cycle.
