Epitaxial mounding in limited mobility models of surface growth
P. Punyindu, Z. Toroczkai, S. Das Sarma
We study, through large scale stochastic simulations using the noise reduction technique, a large number of simple nonequilibrium limited mobility solid-on-solid growth models. We…

Mound formation in nonequilibrium surface growth morphology does not necessarily imply a Schwoebel instability
S. Das Sarma, P. Punyindu, Z. Toroczkai
We demonstrate, using well-established nonequilibrium growth models, that mound formation in the dynamical surface growth morphology does not necessarily imply a surface edge diffu…

A Discrete Solid-on-Solid Model for Nonequilibrium Growth Under Surface Diffusion Bias
S. Das Sarma, P. Punyindu
A limited mobility nonequilibrium solid-on-solid dynamical model for kinetic surface growth is introduced as a simple description for the morphological evolution of a growing inter…
