Topographic phase boundary shifts and saturation for anisotropic ion straggle during sputter etching
Emmanuel O. Yewande, Raphael O. Akande
Surfaces sputtered by ion beam bombardment have been known to exhibit patterns whose behavior is modeled with stochastic partial differential equations. A widely accepted model is…
Numerical analysis of the quantum dots on off-normal incidence ion sputtered surfaces
Emmanuel O. Yewande, Reiner Kree, Alexander K. Hartmann
We implement substrate rotation in a 2+1 dimensional solid-on-solid model of ion beam sputtering of solid surfaces. With this extension of the model, we study the effect of concurr…
Morphological regions and oblique incidence dot formation in a model of surface sputtering
Emmanuel O. Yewande, Reiner Kree, Alexander K. Hartmann
We study solid surface morphology created by off-normal ion-beam sputtering with an atomistic, solid-on-solid model of sputter erosion. With respect to an earlier version of the mo…
Propagation of Ripples in Monte Carlo Models of Sputter Induced Surface Morphology
Emmanuel O. Yewande, Alexander K. Hartmann, Reiner Kree
Periodic ripples generated from the off-normal incidence ion beam bombardment of solid surfaces have been observed to propagate with a dispersion in the velocity. We investigate th…
