Two-dimensional layered materials of transition metal dichalcogenides

Transition metal dichalcogenides (TMDCs) nanomaterials have become a focus of research for their unique properties. Various remarkable properties of TMDCs materials provide possibility for their applications in nanoelectronics, optoelectronics and spintronics devices. This paper mainly introduces the recent advances of TMDCs in different fields with various excellent properties, and summarizes the preparation method, properties and nanostructure morphology of layered TMDCs materials. The edge states of layered TMDCs materials have important effect on the properties, which leads to superior properties different from bulk materials. In this paper, we emphasize the effects of edge states in low dimensional nanomaterials on the properties (chemical activity, electronic property and magnetic property) and the newest progress in edge states. Especially, the magnetic property in edges of TMDCs materials provides the opportunity for their potential usage in the field of magnetism and spintronics, which have aroused great interest of researchers. This paper summarizes the research achievements in TMDCs materials from theoretical and experimental perspectives, which would be supportive for the development of two-dimensional layered TMDCs materials.
