Applications

Atomically thin tungsten disulfide (WS₂) film is a promising material for flexible electronics and optoelectronics owing to light emission in the monolayer form at ~2 eV and the low level of toxicity of growth processes. Thin-layer WS₂ finds application in various fields like lubrication, catalysis, electronics, and energy storage. In lubrication, it's used as a solid lubricant due to its low friction properties. In electronics, WS₂ is employed in semiconductors and as a component in transistors and sensors. Additionally, in catalysis, it's used for its catalytic properties, and in energy storage, it's explored for potential use in batteries and supercapacitors.
