Optical constants of zinc telluride thin films in the visible and near-infrared regions

الملخص EN

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.
