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…
On the Kinetic Roughening in Polymer Film Growth by Vapor Deposition
P. Punyindu, S. Das Sarma
This is a Comment on a recent publication: Y.-P. Zhao et al., Phys. Rev. Lett. 85, 3229 (2000). In the Letter, the authors report on an experimental investigation of polymeric (p-x…
Nonuniversal mound formation in nonequilibrium surface growth
S. Das Sarma, P. Punyindu, Z. Toroczkai
We demonstrate, using well-established nonequilibrium limited-mobility solid-on-solid growth models, that mound formation in the dynamical surface growth morphology does not necess…
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 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…
Noise Reduction and Universality in Limited Mobility Models of Nonequilibrium Growth
P. Punyindu, S. Das Sarma
We show that a multiple hit noise reduction technique involving the acceptance of only a fraction of the allowed atomistic deposition events could, by significantly suppressing the…
