Molybdenum disulfide can also become a new material for making transistors. Compared with graphene, which is also a two-dimensional material, molybdenum disulfide has an energy band gap of 1.8 eV, while graphene does not have an energy band gap. Therefore, molybdenum disulfide may have a broad application space in the field of nanotransistors. Moreover, the electron mobility of the single-layer molybdenum disulfide transistor can reach up to about 500 cm^2/(V s), and the current switching rate...
