Abstract:   (16339 Views)
Thin layers of ZnS in two different temperature conditions of 25 or 2000C and also with different thicknesses from 100nm to 600nm were prepared by physical vapor deposition. Absorption and also transmission spectra of the films were obtained to determine absorption coefficient, extinction constant and optical band gap of the films. It was found that by decreasing the substrate temperature or decreasing the film's thickness, optical band gap of ZnS films were increased or decreased, respectively. These phenomena can be attributed to the quantum size effect.
