Figure 7

The structures after relaxation corresponding to Cu–Gr/R25 (a) and Cu/R25 (d), respectively. The deformed regions of Cu–Gr/R25 and Cu/R25 are singled out with a black oval in panels (a) and (d), and separately shown in panels (b) and (e). The top-view of panel (b) and the vertical view of panel (e) are shown in panel (c) and panel (f), respectively. In the Cu–Gr/R25, the green, red, and blue spheres represent the copper atoms above the graphene, the copper atoms below the graphene, and the carbon atoms of graphene, respectively. In the Cu/R25, the red and green spheres represent the copper atoms on the prefabricated damage layer and the copper atoms of rest region, respectively. For the sake of visualization, the atomic size is not fixed.
