CHAPTER 10: The Family of Two-dimensional Transition Metal Chalcogenides Materials

With atomic thickness and a dangling-bond-free surface, two-dimensional materials exhibit excellent electronic properties and have great potential in the field of next-generation electronics. Five different categories of two-dimensional semiconductors are reviewed in this chapter. We classify various two-dimensional materials by their elemental composition and then discuss their electronic properties and device performance. This classification according to element composition is beneficial to understanding the general characteristics of each category of two-dimensional semiconductors.
