The morphological development of step edge patterns in the presence of meandering instability during step flow growth is studied by simulations and numerical integration of a continuum model. It is demonstrated that the kink Ehrlich-Schwoebel barrier responsible for the instability leads to an invariant shape of the step profiles. The step morphologies change with increasing coverage from a somewhat triangular shape to a more flat, invariant steady state form. The average pattern shape…

Anisotropic dynamics of a vicinal surface under the meandering step instability
We investigate the nonlinear evolution of the Bales-Zangwill instability, responsible for the meandering of atomic steps on a growing vicinal surface. We develop an asymptotic method to derive, in
Growth instabilities of vicinal crystal surfaces during molecular beam epitaxy
In this work the growth instabilities of vicinal crystal surfaces during MBE are studied theoretically. The vicinal surfaces grow in a step-flow mode, where steps present due to a small miscut
Mixing length scales: step meandering and island nucleation on vicinal surfaces
Abstract.Simultaneous island nucleation and step flow growth on vicinal surfaces are studied by Monte Carlo simulations. Step edges experience meandering instability under growth conditions if there
Growth instabilities and adsorbed impurities: A case study
A kinetic Monte-Carlo study of the meandering instability of a vicinal surface growing by step flow is performed. Impurities are codeposited during growth, and they are shown to be responsible for
Double step structure and meandering due to the many body interaction at GaN(0001) surface in N-rich conditions
Growth of gallium nitride on GaN(0001) surface is modeled by Monte Carlo method. Simulated growth is conducted in N-rich conditions, hence it is controlled by Ga atoms surface diffusion. It is shown
Crystal surfaces in and out of equilibrium: A modern view
The last two decades of progress in the theory of crystal surfaces in and out of equilibrium is reviewed. Various instabilities that occur during growth and sublimation, or that are caused by
Evolution of Cu nanoclusters on Cu(100)
Usin gm olecular dynamics simulations combined with kinetic Monte Carlo methods we have studied the evolution of copper nanoclusters on a copper (100) surface. We have developed a method for relaxing
