Geometry of graphene sheet on the Cu(111) surface: a top-fcc, b top-hcp, and c fcc-hcp sites. d Band structures of graphene/Cu(111) system in the top-fcc geometry, compared with e those of free-standing graphene. The magenta points indicate the electronic states contributed from graphene. f The charge differences between total charge density of graphene/Cu(111) and the sum of the charge densities of the independent graphene and the clean Cu(111) surface for the top-fcc geometry. The interval of the contour line is 0.004e Å−3
