MoSe2/graphene heterostructures. a Optical image of the MoSe2/graphene heterostructures on a CaF2 window. The triangles are MoSe2 below a continuous monolayer of graphene. Scale bar represents 100 µm. b Band alignment of the heterostructure. The energy levels CBM (conduction band minimum of MoSe2), Dirac point and Fermi level of graphene, and VBM (valence band maximum of MoSe2) in eV are listed in the order from top to bottom on the right. c Photoluminescence (PL) spectra of the MoSe2 monolayer and MoSe2/graphene heterostructure. PL is severely quenched in the heterostructure
