The effect of irradiation and the depositing substrate temperature on the optical properties of (CuInSeTe) thin films

Abstract

In this research; The effect of irradiation by gamma radiation (0.66 MeV) and the substrate temperature on the optical properties such as (reflectance ,absorption coefficient , extinction coefficient ,refractive index , real and imaginary parts of the dielectric constant) have been studied. These thin films were deposited by the thermal evaporation under vacuum technique on the glass substrates heated at different substrate temperature (Ts=Room Temperature,100 oC,150oC).The study showed that; changing substrate temperature and irradiation process were caused change the optical properties for the prepared thin films.
