“…Intercalation of foreign guest species in transition metal dichalcogenides (TMDs), such as MoS 2 , WS 2 , MoSe 2 , WSe 2 , et al, is beginning to attract considerable interest. This is in part due to the novel electronic properties of these systems enabling prospective applications to high-performance electronics, optoelectronics, electrochemical catalysis, energy storage and conversion (such as ionic batteries), and biological systems. − In this context, studies of intercalation specifically for MoS 2 have attracted considerable attention. , On the other hand, TMD nanosheets are often fabricated by intercalation, and various methods toward this goal have been utilized. , Also, there do already exist extensive studies of near-surface intercalation in other types of layered van der Waals (vdW) materials, including graphite (or multilayer graphene) and SiC- , or metal-supported graphene layers. The above studies − generally involve homogeneously distributed intercalant atoms in the TMD interlayer spaces.…”
