دراسة الخصائص البصرية لغشاء رقيق من ZnTe محضر بطريقة الرش الكيميائي الحراري

Abstract

In this study, thin films of ZnTe were deposited on glass substrates using thermal spray pyrolsis technique. The optical measurements on the deposited films were performed to determine the transmission spectrum and the absorption coefficient as a function of incident wavelength. Then from the optical parameters, extinction coefficient, value and type of energy gap, type of the dominant absorption processes, real and complex refractive index as functions of incident photon energy, were determined. The Energy gap is found to be equal to 2.26eV that is direct transfer. this results is similar to the results given by other researchers.
