This paper reports on the synthesis of thin films tungsten disulfide (WS 2 ) by сhemical vapour deposition (CVD) using powders sulfur and oxide obtained from metal powder. It is shown that synthesized ultra-thin 2-dimensional (2D) WS have appropriate structural optical properties suitable for their application in manufacturing electronic optoelectronic devices. Proposed method 2D few-layered can significantly accelerate rate will make it possible to control stoichiometry shapes nanocrystals controlling amount magnetic mechanism. Moreover, crystals demonstrate long-term stability external factors, since research carried out during year. During this time, no signs degradation TMDs structure were detected.
