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.

Abstract: We studied helicity-resolved Raman scattering in PtSe2 flakes with different thicknesses. The peak amplitude of helicity-switched Raman scattering is significantly larger than that of helicity-conserved scattering for the in-plane E g mode, consistent with the… read more here.
