Abstract

This paper delves into the abnormal surface diffusion of particles in external time-periodic field. The relationship of surface diffusion enhancement as a function of amplitude and frequency of external fields has been studied. It has been shown that the diffusion coefficient can significantly be increased (by several orders of magnitude) by applying external time-periodic fields. The diffusion gain ratio considerably depends on the surface temperature, external field amplitude and frequency.
