متن کاملDiffusion of adsorbates on metal surfaces
The theory of diffusion and the principal methods of determining surface diffusion coefficients are presented and their strengths and weaknesses discussed. A summary of major experimental results for diffusion of metallic and non-metallic adsorbates on metal surfaces is given and areas of agreement and disagreement between various measurements are discussed. A brief overview of principal conclu...

متن کاملAtomic assembly of metal surfaces and interfaces
Inert gas ion impacts can be used to manipulate atomic assembly processes during the growth of metallic superlattices but the detailed mechanisms are not well understood. Molecular dynamics simulations are used to investigate the effects of ion incident angle and fluence upon the reassembly and structure of a copper surface partially covered with cobalt asperities. In the low ion energy regime,...
متن کاملDimer Shearing as a Novel Mechanism for Cluster Diffusion and Dissociation on Metal (100) Surfaces.
Using bond-counting arguments and embedded-atom calculations, we establish the crucial importance of dimer shearing in metal (100) submonolayer epitaxy. This process provides the easiest pathway for diffusion of compact clusters of sizes 4, 6, and 8, and introduces a rich variety of localized cluster dynamics. A combination of the dimer shear motion and the traditional mechanism of sequential m...
