Molybdenum disulfide is an important solid lubricant and is especially suitable for high temperature and high pressure. It is also diamagnetic and can be used as a linear photoconductor and a semiconductor exhibiting P-type or N-type conductivity, with rectification and transduction. Molybdenum disulfide can also be used as a catalyst for the dehydrogenation of complex hydrocarbons.
The main function of molybdenum disulfide for friction materials is to reduce friction at low temperature, increase friction at high temperature, and reduce ignition loss, which is volatile in friction materials.
In addition, molybdenum disulfide can also be a new material for making transistors. Compared with graphene of the same two-dimensional material, molybdenum disulfide has a band gap of 1.8 eV, while graphene has no band gap. Therefore, molybdenum disulfide may have a wide application space in the field of nano-transistors. Moreover, the single-layer molybdenum disulfide transistor has an electron mobility of up to about 500 cm^2/(V·s) and a current switching rate of 1×10^8.
