Abstract
Molybdenum sulphide thin films were cathodically electrodeposited from aqueous solutions of sodium tetrathiomolybdate on quartz substrate covered by a thin Ni–Cr layer. Annealing of these films in sulphur containing atmosphere at high-temperature resulted in the formation of highly-textured films of MoS 2 with the van der Waals planes parallel to the substrate and crystal size in the micrometer range. The annealed films are photoactive and their photoconductivity measurements reveal a direct band gap of about 1.71 eV.
