| Research Abstract |
Superlubricity of C60/graphene and graphene/graphene interfaces is studied by molecular mechanics simulation. First, for superlubricity of (graphene)n/C60/(graphene)n interface, difference between multilayer (n>1) and monolayer (n=1) systems are found. For monolayer, superlubricity is derived from only stacking relation between C60 and graphene. However, for multilayer, superlubricity is also derived from that between graphene and graphene, which opens an lower energy path. Next, it is found by theory and experiment that, for peeling and adhesion of graphene sheet, quasiperiodic lateral force curve is obtained due to stick-slip motion during surface contact region, whose period nearly corresponds to the lattice constant of graphite.
