In this study, thin films of ZnTe were deposited on glass substrates using
vacuum evaporation technique. The optical measurements on the deposited films
were performed to determine the transmission spectrum and the absorption spectra
as a function of incident wavelength. As well, optical parameters, such as
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. This study may present better understanding for
the optical properties of ZnTe thin films and their devices in order to enhance their
characteristics and improve their efficiencies.
