Here, the authors investigate the interfacial charge/energy transfer dynamics in a WSe2/graphene heterostructure. They unveil an energy transfer mechanism from WSe2 to graphene mediated by an interfacial Meitner-Auger process, resulting in a transient hole distribution in the Dirac cone at energies larger than the photon energy of the optical excitation.
