Crater functions for compound materials: a route to parameter estimation in coupled-PDE models of ion bombardment
Scott A. Norris, Juha Samela, Matias Vestberg +2
During the ion bombardment of targets containing multiple component species, highly-ordered arrays of nanostructures are sometimes observed. Models incorporating coupled partial di…
Stress-induced patterns in ion-irradiated Silicon: a model based on anisotropic plastic flow
Scott A. Norris
We present a model for the effect of stress on thin amorphous films that develop atop ion-irradiated silicon, based on the mechanism of ion-induced anisotropic plastic flow. Using…
Stability analysis of a viscoelastic model for ion-irradiated silicon
Scott A. Norris
To study the effect of stress within the thin amorphous film generated atop Si irradiated by Ar+, we model the film as a viscoelastic medium into which the ion beam continually inj…
A Mean-Field Theory for Coarsening Faceted Surfaces
Scott A. Norris, Stephen J. Watson
A mean-field theory is developed for the scale-invariant length distributions observed during the coarsening of one-dimensional faceted surfaces. This theory closely follows the Li…
The Kinematics of Completely-Faceted Surfaces
Scott A. Norris, Stephen J. Watson
We fully generalize a previously-developed computational geometry tool [1] to perform large-scale simulations of arbitrary two-dimensional faceted surfaces . Our method…
