a Snapshots of the tip sliding on the roughened substrate supported graphene for the two cases examined taken during loading at 10 nN applied load. b Load dependent friction curve obtained from MD simulations for the low and high interaction cases. c Strain map of graphene in the (top) loading and (bottom) unloading periods at 10 nN applied load for the two cases examined. d The number of contacting atoms between the sliding tip and the graphene film during loading and unloading measurements for the two cases.
