Van der Waals Heterostructures: WS2 and Graphene Synergy in Optoelectronics metal alloy
Tungsten disulfide (WS2) is a transition metal sulfide compound belonging to the family of two-dimensional change steel sulfides (TMDs). It has a direct bandgap and appropriates for optoelectronic and digital applications. (Tungsten Disulfide) When graphene and WS2 integrate with van der Waals forces, they form a special heterostructure. In this structure, there is no covalent…
