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…
