Abstract:

Graphene-like two-dimensional (2D) transitional metal dichalcogenides(TMDCs) have attracted a wide range of research passions. After the dramatic success of graphene, molybdenum disulfide(MoS2) is one of the most typical TMDCs. It’s a wide direct bandgap of 1.8ev in monolayer and layer dependence band structure, very low noise, scalability, transparency. Most importantly, it is stiff as stainless steel but capable of being flexible, stretched up to 10% of its length, and bent to a large angle. These tackle the gapless problems over graphene. At the same time, several high-thoughtful studies have focused on understanding the relative activities of various TMDCs. So the interactions of Metal-TMDC are less well studied.
