The mos2 melting point is the temperature at which molybdenum disulfide (MoS2) crystals melt. This is an important property to consider when designing optoelectronic devices such as photodetectors, FETs, sensors and valleytronics.
Unlike most materials, the mos2 melting point is determined by the band structure of each layer. This can significantly affect the optical properties of a monolayer, which can be a huge advantage when developing photodetectors, optoelectronic devices and sensors with large fields of view, such as those operating in the visible region.
It is therefore important to know how to synthesise molybdenum disulfide at a low cost and high quality. There are a number of different methods that can be used to obtain MoS2 in the form of thin films, including mechanical exfoliation, liquid exfoliation and physical vapour deposition.
In general, mechanical exfoliation involves the use of a sticky tape that is rubbed out and then shifted on a substrate covered with MoS2 flakes. This method has a low yield but is simple and cheap to use for lab applications. Alternatively, liquid exfoliation can be performed by adding a chemical compound to MoS2 and stirring, bubbling or grinding it in water. However, the pyrophoric nature of liquid exfoliation may limit its scalability for producing large area layers. Sonication is another alternative that uses ultrasound emitted by a probe to peel MoS2 layers. The technique has the potential to be a simple and scalable method that produces large area crystalline layers that have high optical properties comparable to those obtained using other top-down synthesis methods.
