Abstract
Copper indium disulfide (CuInS2) thin films were thermally and chemically prepared, and the structural, optical and electrical properties were investigated. X-ray analysis indicates only single-phase chalcopyrite with no extra planes. The optical and the thermal energy gap was determined. The gap of the annealed thermally-prepared samples in sulfur vapour is greater than of the as-deposited films, which indicates the decrease of d-level contribution to the valence band.
