Single-Particle Diffusion-Coefficient on Surfaces with Ehrlich-Schwoebel-Barriers
K. Mussawisade, T. Wichmann, K. W. Kehr
The diffusion coefficient of single particles in the presence of Ehrlich-Schwoebel barriers (ESB)is considered. An exact expression is given for the diffusion coefficient on linear…

Diffusion Coefficients of Single and Many Particles in Lattices with Different Forms of Disorder
K. W. Kehr, T. Wichmann
A survey is given on asymptotic diffusion coefficients of particles in lattices with random transition rates. Exact and approximate results for single particles are reviewed. A rec…
