Molybdenum Disulfide as New Material of Optical Equipment

Graphene has a lot of great properties, but it lacks of conductivity and optical property. So there are fewer applications about graphene in high-tech equipment. Chemists and materials scientists have tried to find other materials which can exceed graphene as new material. After researches, now scientists are focus on molybdenum disulfide and black phosphorus research and these two kinds of materials both have great electronic property.

In 2008, it was the first time that molybdenum disulfide (MoS2) be synthesized. MoS2 is one of family members of transition metal disulfide material (TMDs). MoS2 not only thin which is similar to graphene but it also is a kind of good semiconductor. The electron of molybdenum disulfide in planar wafer’s running speed, namely, electronic mobility is about 100cm2/vs. Comparing with crystalline silicon (1400 cm2/vs) the electronic mobility of it is slower Cemented Carbide Inserts but comparing with amorphous silicon and other ultra-thin semiconductor the electronic mobility is higher. Scientists try to make it applies in future electronic products such as flexible displays and other flexible electronic products. With research development, scientists try to deal with slow electronic mobility speed of MoS2 and to produce multilayer MoS2 films so there has another selection path for compressed electronic to avoid roadblock and to increase electronic mobility. On the other hand, MoS2 is kind of direct wide gap material and this property can direct transform electronic to photon or transform photon to electronic. So it becomes preferred material applying in optical equipments, such as optical transmitting set, laser, photoelectric detector and solar cells.
