Application
Tungsten disulfide (WS2) in bulk has been used for many years as a dry lubricant due to how it exhibits properties of a low coefficient of friction, high chemical stability, and thermal stability. In 1992, it was discovered that the structure of WS2 made it capable of forming nanotube structures. These nanotubes were the first examples of WS2 being used as a low-dimensional material.
After the discovery of simple mechanical exfoliation techniques to isolate single layers of 2-D materials, it was possible to study the properties of WS2 flakes. It was shown that, just like MoS2, the band-gap of WS2 change from an indirect band-gap of 1.4eV to a direct band-gap of 2eV when changing from a bulk material to a 2-D material. Due to its band-gap, WS2 is seen as a significantly interesting material for many areas of application.
WS2 possesses a high on/off ratio in field-effect transistors, controllable spin and valley polarisation, strong geometrical confinement of excitons, and tunable photoluminescence. Additionally, WS2 could lead to increased interest in areas such as photodetectors and multi-junction photovoltaics.
Besides, WS2 is used, in conjunction with other materials, as catalyst for hydrotreating of crude oil.
Lamellar tungsten disulfide is used as a dry lubricant for fasteners, bearings, and molds under the brand name Dicronite.
