Abstract

Thermal evaporation technique was used to deposit (Ga_0.1In_0.9)₂Se₃ thin films. The optical transmission spectra of (Ga_0.1In_0.9)₂Se₃ thin film were studied in the temperature range 77-300 K. Temperature behaviour of the Urbach absorption edge as well as the temperature dependencies of the energy pseudogap and Urbach energy were investigated. The influence of different types of disordering on the optical properties of (Ga_0.1In_0.9)₂Se₃ thin film was discussed. Optical parameters of (Ga_0.1In_0.9)₂Se₃ thin film and single crystal were compared.
