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…
Off-lattice noise reduction and the ultimate scaling of DLA in two dimensions
Robin C. Ball, Neill E. Bowler, Leonard M. Sander +1
Off-lattice DLA clusters grown with different levels of noise reduction are found to be consistent with a simple fractal fixed point. Cluster shapes and their ensemble variation ex…
