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…
Influence of Collision Cascade Statistics on Pattern Formation of Ion-Sputtered Surfaces
M. Feix, A. K. Hartmann, R. Kree +2
Theoretical continuum models that describe the formation of patterns on surfaces of targets undergoing ion-beam sputtering, are based on Sigmund's formula, which describes the spat…
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…
Long-Time Effects in a Simulation Model of Sputter Erosion
Alexander K. Hartmann, Reiner Kree, Ulrich Geyer +1
A simple (2+1) dimensional discrete model is introduced to study the evolution of solid surface morphologies during ion-beam sputtering. The model is based on the same assumptions…
