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…
Combination of random-barrier and random-trap models
K. Mussawisade, T. Wichmann, K. W. Kehr
The temperature dependence of the diffusion coefficient of particles is studied on lattices with disorder. A model is investigated with both trap and barrier disorder that was intr…
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…
Iterated Function System and Diffusion in the Presence of Disorder and Traps
Thomas Wichmann, Achille Giacometti, K. P. N. Murthy
The escape probability from a site of a one-dimensional disordered lattice with trapping is treated as a discrete dynamical evolution by random iterations over nonlinea…
