Step bunches, nanowires and other vicinal “Creatures”—Ehrlich–Schwoebel effect by cellular automata

M Załuska-Kotur, H Popova, V Tonchev - Crystals, 2021 - mdpi.com
Different patterns can be created on the surface of growing crystals, among which the step
bunches and/or step meanders are two of the most studied. The Ehrlich–Schwoebel effect at …

Diffusion-Dependent Pattern Formation on Crystal Surfaces

MA Chabowska, MA Załuska-Kotur - ACS omega, 2023 - ACS Publications
The growth of a crystal is usually determined by its surface. Many factors influence the
growth dynamics. Energy barriers associated with the presence of steps most often decide …

Unstable vicinal crystal growth from cellular automata

A Krasteva, H Popova, F Krzyżewski… - AIP Conference …, 2016 - pubs.aip.org
In order to study the unstable step motion on vicinal crystal surfaces we devise vicinal
Cellular Automata. Each cell from the colony has value equal to its height in the vicinal …

[HTML][HTML] Two-dimensional cellular automata—Deterministic models of growth

P Lazzari, N Seriani - Chaos, Solitons & Fractals, 2024 - Elsevier
Cellular automata are simple discrete deterministic rules that can however produce different,
from simple to very complex, dynamics, and it would be useful to have a criterion to classify …

Analyzing the Pattern Formation on Vicinal Surfaces in Diffusion-Limited and Kinetics-Limited Growth Regimes: The Effect of Step–Step Exclusion

H Popova - Crystal Growth & Design, 2023 - ACS Publications
The effect of step–step exclusion on growing vicinal surfaces destabilized by a step-up (SU)
or step-down (SD) driving force is extensively studied in diffusion-limited (DL) and kinetics …

Fourier analysis of Turing-like pattern formation in cellular automaton models

S Dormann, A Deutsch, AT Lawniczak - Future Generation Computer …, 2001 - Elsevier
The novelty of this paper is the study of emergence of diffusion-induced (Turing-like)
patterns from a microscopic point of view, namely, in terms of cellular automata. Formally …

A conjecture about the size of a particular cellular automaton: the perfectly growing crystal

H Dreyssé, R Riedinger - Journal de Physique, 1987 - jphys.journaldephysique.org
In order to optimize a computer implementation of the recursion method,(initially proposed
by Heine, Haydock and Kelly), we build a cluster from an initial seed of points by adjoining …

Reaction-diffusion cellular automata model for the formation of Leisegang patterns

B Chopard, P Luthi, M Droz - Physical review letters, 1994 - APS
Cellular automata models for the formation of Liesegang structures are proposed. This novel
approach, which takes into account the fluctuations for the first time, describes the problem …

Physically derived rulesfor simulating faceted crystal growth using cellular automata

KG Libbrecht - arXiv preprint arXiv:0807.2616, 2008 - arxiv.org
We derive a set of algorithms for simulating the diffusion-limited growth of faceted crystals
using local cellular automata. This technique has been shown to work well in reproducing …

A local cellular model for growth on quasicrystals

P Chidyagwai, CA Reiter - Chaos, Solitons & Fractals, 2005 - Elsevier
The growth of real valued cellular automata using a deterministic algorithm on 2-
dimensional quasicrystalline structures is investigated. Quasicrystals are intermediate …
