Abstract
We employed the VicCA model to investigate the influence of step-edge potential on nucleation and pattern formation, aiming to gain deeper insights into island formation and growth. Our study explores fractal structures governed by general cellular automaton (CA) rules, as well as compact structures shaped by density-dependent attachment mechanisms. We demonstrate that modifications to the CA framework have a significant impact on surface patterning, emphasizing the critical role of adatom attachment rules and the substantial effect of potential well depth on the resulting surface morphology.
