Description and Uses

Few-layer molybdenum disulfide (MoS2) is considered to be one of the most attractive?materials?for next-generation nanoelectronics. This is due to its silicon-level charge mobility and high current on/off ratio in thin-film transistors. Compared to monolayer? MoS2 (which needs?a deposition of an additional high-k?dielectric layer such as HfO2), few-layer?MoS2 can be operated on its own. This makes it more appealing for fabricating transistors and other optoelectronic devices.

Dry lubricant and lubricant additive. Hydrogenation catalyst.
