Abstract
Spinel AgIn 5 S 8 and CuIn 5 S 8 materials are perspective for application in optoelectronic semiconductor devices. For the first time, thin films of these compounds were grown and investigated. The films were deposited by a sequential process on Mo-coated soda lime glass. This process consists of sulphur vapour sulphurization of a metallic alloy precursor. We found that a good adhesion to the substrate (Mo-coated glass) could be achieved by introduction of a Ti layer between the substrate and the spinel layer. The spinel layers have been investigated by XRD and XPS methods. Moderate roughness of the films and a crystallite size of about 200-400 nm were observed in the AFM images.
