Formation of pyrite (FeS2) thin nano-films by thermal-sulfurating electrodeposition films at different temperature

The electrodeposition of iron disulfide pyrite (FeS2) thin films on indium–tin oxide (ITO) substrate in aqueous solution containing Na2S2O3·5H2O, FeCl2·4H2O reagents was investigated. The deposited material is successively annealed in sulfur atmosphere. In this way, we successfully obtained pyrite thin films with good quality. The structure, optical and electrical property analysis for the resulted films was carried out and some special results have been concluded.
