Abstract: Helicity-resolved ultrafast spectroscopy reveals complex charge/spin dynamics in TMD/graphene heterostructures. Transition metal dichalcogenide (TMD)/graphene (Gr) heterostructures constitute a key component for two-dimensional devices. The operation of TMD/Gr devices relies on interfacial charge/energy transfer processes, which… read more here.
