Abstract

(Ga_0.3In_0.7)₂Se₃ films were deposited by the thermal evaporation technique. As-deposited (Ga_0.3In_0.7)₂Se₃ films were irradiated using wideband radiation of Cu-anode X-ray tube at different exposure times. The spectral dependences of refractive index and extinction coefficient were measured by the spectral ellipsometry technique. The optical transmission spectra of X-ray irradiated (Ga_0.3In_0.7)₂Se₃ films were studied depending on irradiation time. Parameters of Urbach absorption edge for X-ray irradiated (Ga_0.3In_0.7)₂Se₃ thin films were determined and compared with nonirradiated film. The spectral dependences of refractive indices of non-irradiated and X-ray irradiated (Ga_0.3In_0.7)₂Se₃ films are described in the framework of Wemple and DiDomenico model. TThe variation of the parameters of Wemple and DiDomenico model for non-irradiated and X-ray irradiated (Ga_0.3In_0.7)₂Se₃ films was discussed.
