We measured energy distribution and yields of electrons emitted from graphene adsorbed on a Ni(111) surface under the impact of 200–1200 eV electrons. The adsorption of graphene results in significant changes of the spectra of emitted electrons but not of the total emission yields. The electronic structure of the graphitic overlayer determines the final states of excited electrons transported by collision cascade from the bulk of the substrate.
