| Outline of Final Research Achievements |
In order to investigate the influence of graphene curvature on superlubricity, molecular mechanics simulation of peeling process of monolayer graphene sheet adsorbed onto the graphite substrate was carried out. As the initial orientation angle of the graphene adsorption is varied little by little from the AB stacking orientation, the effect of lattice mismatch of the surface contact area appears, and the mean lateral force during the surface contact process markedly decreases to about 0 pN for the orientation angle of 9 deg. For larger orientation angle, the mean lateral force changed only slightly around 0 pN.
