From: Kinetic nanofriction: a mechanism transition from quasi-continuous to ballistic-like Brownian regime

Figure 1

MD simulations of surface diffusion in C 60 /graphene system. (a) The side view of a C60 molecule above a graphene sheet. The inset shows the top view. (b-d) Four nanosecond trajectories of C60 at (b) ultra-low temperature regime. Single hopping mechanism is dominant at 5 K, which gradually turns to multiple jumps up to 25 K. Even at 15 and 25 K, some signs of quasi-continuous motion are observable. (c) Low temperature regime, which shows quasi-continuous Brownian motion (Regime III). (d) High temperature regime, which shows ballistic-like Brownian motion (Regime IV).
