Vacancy diffusion in the Cu(001) surface I: An STM study
R. van Gastel, E. Somfai, S. B. van Albada +2
We have used the indium/copper surface alloy to study the dynamics of surface vacancies on the Cu(001) surface. Individual indium atoms that are embedded within the first layer of…

Nothing moves a surface: vacancy mediated surface diffusion
R. van Gastel, E. Somfai, S. B. van Albada +2
We report scanning tunneling microscopy observations, which imply that all atoms in a close-packed copper surface move frequently, even at room temperature. Using a low density of…

Strain in heteroepitaxial growth
E. Somfai, L. M. Sander
We use atomistic simulations with an empirical potential (EAM) to study the elastic effects of heteroepitaxial islands on adatom diffusion. We measure the diffusion barrier on pure…
