Tungsten disulfide - Wikipedia

2020-12-19 · Tungsten disulfide is an inorganic chemical compound composed of tungsten and sulfur with the chemical formula WS 2.This compound is part of the group of materials called the transition metal dichalcogenides.It occurs naturally as the rare mineral tungstenite.This material is a component of certain catalysts used for hydrodesulfurization and hydrodenitrification.

Preparation and Photoluminescence of Tungsten …

Tungsten disulfide (WS2) monolayer is a direct band gap semiconductor. The growth of WS2 monolayer hinders the progress of its investigation. In this paper, we prepared the WS2 monolayer through chemical vapor transport deposition. This method makes it easier for the growth of WS2 monolayer through the heterogeneous nucleation-and-growth process.
