Spiral Evolution in a Confined Geometry
Madhav Ranganathan, D. B. Dougherty, W. G. Cullen +3
Supported nanoscale lead crystallites with a step emerging from a non-centered screw dislocation on the circular top facet were prepared by rapid cooling from just above the meltin…
From Discrete Hopping to Continuum Modeling on Vicinal Surfaces with Applications to Si(001) Electromigration
T. Zhao, J. D. Weeks, D. Kandel
Coarse-grained modeling of dynamics on vicinal surfaces concentrates on the diffusion of adatoms on terraces with boundary conditions at sharp steps, as first studied by Burton, Ca…
A Two-Region Diffusion Model for Current-Induced Instabilities of Step Patterns on Vicinal Si(111) Surfaces
T. Zhao, J. D. Weeks
We study current-induced step bunching and wandering instabilities with subsequent pattern formations on vicinal surfaces. A novel two-region diffusion model is developed, where we…
A unified treatment of current-induced instabilities on Si surfaces
Tong Zhao, John D. Weeks, Daniel Kandel
We introduce a simple two region model where the diffusion constant in a small region around each step on a vicinal surface can differ from that found on the terraces. Steady state…
