• AgInSe_2 thin films have been deposited on glass substrates from an evaporation source of alloy chunks at various substrate temperatures. In the deposition process, atomic and molecular species of Se and In evaporate first, followed by Ag. The components react with each other on the substrate to form Ag-In-Se alloys at elevated temperatures. The crystal structure varies depending on the substrate temperature. Above 400℃, chalcopyrite-type crystallites of AgInSe_2 were found to be dominant in the film, and there were very few of sphalerite-type. On the whole Se atoms were deficient in the films. Co-evaporation of Se with the alloy chunks followed by additional annealing produces a film containing only chalcopyrite crystallites. The optical absorption edge could be clearly observed both in the transmission and the photoconductance spectra. Electrical properties are discussed.
