Surface diffusion an—Exercise in D = 2 + 1 dynamics

The diffusion of particles on surfaces of solids play important role in understanding variety of phenomena, which are of considerable theoretical and applied interest. For example surface diffusion may alter the mode of the morphological structure via which crystal growth progresses. Study of surface diffusion, and more generally dynamics of many particle systems on solid surfaces may also offer an insight into the more fundamental problems, for example how many particle dynamics is affected by change of the spatial dimensionality.
