Abstract

Highly crystalline thin films of Cu₂(Zn_yFe_1−y)SnS₄ (CZFTS), Cu₂(Zn_yFe_1−y)SnSe₄ (CZFTSe) and Cu₂(Zn_yFe_1−y)Sn(S_xSe_1−x)₄ (CZFTSSe) have been deposited by aerosol assisted chemical vapour deposition (AACVD) from mixtures of dithio- or diseleno-carbamato, diselenophosphinato and acetylacetenato complexes. The structure, morphology, composition, optical and electrical properties of the deposited materials were investigated. The [Zn] : [Fe] and [S] : [Se] ratios are the important factors affecting the overall properties of these materials and can be controlled.
