Vacancy diffusion in the Cu(001) surface II: Random walk theory
E. Somfai, R. van Gastel, S. B. van Albada +2
We develop a version of the vacancy mediated tracer diffusion model, which follows the properties of the physical system of In atoms diffusing within the top layer of Cu(001) terra…
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…
