▎ 摘　　要

We present an angle-resolved electron-energy-loss study of the graphene/Ni(110) system. The dispersion curve of the it plasmon, compared with that obtained for graphene synthesized on the Ni(111) surface, shows that in both systems the nature of the oscillating charge at the interface is confined in a two-dimensional layer, but in the case of graphene grown on Ni(110) the interaction with the substrate is weaker. We assign this behavior to a weaker graphene-nickel hybridization in the case of Ni(110), due to the lack of long range matching between the two-dimensional lattices of graphene and nickel.
