Abstract
Anomalous diffusion of a gold nanocrystal , adsorbed on the basal plane of graphite, exhibiting Lévy-type power-law flight-length and sticking-time distributions, is predicted through extensive molecular dynamics simulations. An atomistic collective slip-diffusion mechanism is proposed and analyzed.
