Abstract The present research is focused on the elaboration of laser technology for phase transition in Sn-S binary system in order to form n-SnS2/p-SnS heterojunction. With this purpose, the SnS2 films deposited on ITO coated glass substrates by close spaced sublimation method were irradiated by the Nd:YAG laser. The analysis of the samples by Raman spectroscopy shows phase transition of near-surface layer from SnS2 to SnS after irradiation. Moreover, the electrical study of irradiated samples reveals diode behavior of the current-voltage characteristic of Al/sample/ITO sandwich structure which was explained by formation of heterojunction.
