Diffusion on and , Surfaces: The Atomic Slide Puzzle,ted motion of terrace atoms shows there must be an attractive interaction between an embedded In atom and a vacancy, which makes the In atom somewhat more mobile than a Cu surface atom. Such an attraction is indeed found in Embedded Atom Method calculations.

1568-2609 is on to the problem of surface diffusion. Clearly surface diffusion is the key process, which determines how atoms move on the surface. Controlling this motion can lead to the easy fabrication of well-controlled nanostructures broadening the present possibilities in nanotechnology. The paradigm of

The possible mechanism and schemes of particle migration and corresponding diffusion processes are discussed.

S. Sivier,J. Baum,E. Loth,R. Löhner220 K). A surprisingly sharp transition to the quasi-2D decay mode was observed around 220 K. This transition was accompanied by a fast equilibration of the island shape. These findings have tentatively been rationalized within a simple model to identify the underlying rate limiting atomistic processes.
