Preparation of the Stoichiometric SnS2 and SnS Thin Films Using Spin-coating-pyrolysis Method at the Appropriate Pyrolysis Temperature

In this paper, the stoichiometric SnS 2 and SnS thin films were successfully prepared using spin-coating-pyrolysis method and the appropriate pyrolysis temperature were 260 ℃ of SnS 2 and 320 ℃ of SnS. The atomic ratios of Sn/S for SnS 2 and SnS thin films were 1:1.98 and 1:0.99. The stoichiometric SnS 2 thin film exhibited the morphology with the bilayer structure, the bottom layer was compact and the upper layer was porous.
