Computer modeling of mass transport along surfaces.

This chapter contains a review of recent simulation studies of surface diffusion. It includes a discussion of surface segregation and roughening transitions and their impact on surface mass transport, mainly within the context of the Ising model. Results obtained from molecular dynamics simulations of crystal surfaces are also reviewed. Particle diffusion and mass transport rates in near-surface layers of close-packed crystallographic orientations are treated, and also the formation of quasi-liquid layers near the triple point.
