Layer by layer epitaxy in limited mobility nonequilibrium models of surface growth

Abstract

We study, using noise reduction techniques, layer by layer epitaxial growth in limited mobility solid-on-solid nonequilibrium surface growth models, which have been introduced in the context of kinetic surface roughening in ideal molecular beam epitaxy. Multiple hit noise reduction and long surface diffusion length lead to qualitatively similar layer by layer epitaxy in 1+1 and 2+1 dimensional limited mobility growth simulations. We discuss the dynamic scaling characteristics connecting the transient layer by layer growth regime with the asymptotic kinetically rough growth regime.
