SnS films have been prepared by a novel two-stage process. It involved sputtering of Sn film on glass substrate and sulfurization of the thin metallic tin precursor layers in a vacuum furnace. The X-ray diffraction results showed that the SnS layers had orthorhombic structure and (0Â 4Â 0) preferential growth is more and more obvious with the increase of sulfurization time. The SnS film obtained by this work shows high optical absorption efficiency, and the film has a direct optical band gap of about 1.3Â eV. The films show p-type conductivity and the resistivity of SnS film decreased obviously under illumination.
Research highlightsâ¶ SnS film without any other phases was successfully prepared by two-stage sulfurization method. â¶ The effect of sulfurization time on the SnS film's property was systematically studied. â¶ The prepared SnS film shows obvious photoresponse effect â¶ Persistent photoconductivity of SnS film was detected in this work.
