Two-Dimensional Transition Metal Dichalcogenides and Their Advanced Transistors

With the found of graphene, people got great interest in its properties. But as no band gap exists in graphene, it’s not easy to be used in semiconductor production. Inspired by its disjuncture, transition metal dichalcogenides (TMDs) are developed which have many fascinating properties. Meanwhile, silicon gradually reaches its physical limits. As the feature size of silicon transistors gets smaller, silicon devices are becoming more complicated and their cost and energy consumption keeps rising. Finding a new material to take silicon’s place puts on the agenda TMDs show potential in producing high-frequency devices and have lower energy consumption. Using TMDs in high-speed devices makes great hope to keep Moore’s law. It also can be used in other areas like photodetection. This article gives a full and concise review of TMDs from what TMD is, its mechanism and properties, how to produce it, devices made by TMDs to problems they face.
