Abstract
⺠The rapid diffusion in nanoparticles were reproduced by MD simulations. ⺠The atomistic diffusion mechanism in a metal cluster is Surface Peeling Mechanism. ⺠In contrast, the diffusion mechanism in an alkali halide cluster is Vacancy Mechanism. ⺠The vacancy formation energy of metal clusters increases as their size decreases, while that of alkali halides decreases. ⺠This opposite trend is a reason for the onset of the totally different mechanisms.
