Açıklama
The Cu2SnS3(CTS) thin films were produced by deposition of Sn/Cu layers by RF sputtering followed by annealing in an Ar/S atmosphere with S and Sn sources. According to XRD analysis and Raman spectroscopy, it was shown that single-phase CTS films of a monoclinic structure with traces of the CuxS phase were formed at a temperature of 520 degrees C. Scanning electron microscopy revealed a compact and homogeneous microstructure of the polycrystalline CTS layers. Photoluminescence spectra of the CTS films of monoclinic modification show one wide peak in the energy range of 0.7-1.0 eV, due to optical transitions of electrons from the conduction band to deep energy levels of acceptor-type defects.
