Electrical switching between exciton dissociation to exciton funneling in MoSe2/WS2 heterostructure

Electrical switching between exciton dissociation to exciton funneling in MoSe2/WS2 heterostructure

The ultrafast carrier dynamics across the van der Waals interface of transition metal dichalcogenide heterostructures govern the formation and funnelling of excitons. Here, the authors demonstrate a reversible switch from exciton dissociation to exciton funnelling in a MoSe2/WS2 heterostructure, whi...
