Effect of surface roughness on adhesion of graphene membranes


A theoretical model is presented to predict how the surface roughness may affect the adhesion between graphene membranes and their substrates. The bending modulus, which increases drastically from monolayer to multilayered graphene, plays an important role in the transition from conformal to non-conformal morphology of the graphene membranes on a corrugated surface. As such, the measurable adhesion energy drops considerably from monolayer to bilayer graphene. Moreover, the results suggest that tunable adhesion of graphene can be achieved by controlling the surface roughness of the substrate.
