Other synthesized of MoS2


MoS2 is synthesized using a liquid organic precursor on an insulating substrate using CVD. The method used is more reproducible and is used to obtain larger areas of MoS2 layers than those obtained with methods using powder Molybdenum oxide and sulfur powder. Another method is used thermal evaporation and ALD, which uses metalloporphyrin as a promoter layer. The method allowed us to manipulate the carrier density and conductivity of MoS2 according to the thickness of the metalloporphyrin layer. It is used to produce MoS2 nanosheets on a large scale. MoS2 is synthesized using self-propagating, under high temperature, where Mo nanopowders and elementary Sulfur are used. The mixture is put into cylinders and then under pressure. The resulting main structure is 2H MoS2, but there are other phases like rhombohedral MoS¬2 and Mo2S3. Thermal sulfidation is another method like CVD that uses Sulfur gas as a precursor. It uses a Mo or Mo-oxide film deposited on a substrate, where evaporated Sulfur passes over it under a certain temperature. The method reduces the effect of gas flows in CVD and results in self-aligned patterns of MoS2. The sulfidation of two different oxides of Mo: MoO3 and MoO2 discussed showed more stable MoS2 monolayer films produced from MoO2. The films were integrated with bottom-gate transistors, showing an on/off ratio of 103–104 and electron mobility of 10−4 cm2/V·s. The PL spectrum of the synthesized monolayers has an exciton peak at 1.89 eV.
