Complex surface patterning in homo- and heteroepitaxial contexts: (simultaneous) step bunching and step meandering
Vassil Ivanov, Vesselin Tonchev, Marta A. Chabowska +2
We confront a meso-scale continuum model, archetypical for the heteroepitaxial context, with an atomistic Vicinal Cellular Automaton (VicCA), built as a homoepitaxial counterpart,…
Engineering 2D Surface Patterns with the VicCa Model
Marta A. Chabowska, Magdalena A. ZaÅuska-Kotur
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…
Step meandering: The balance between the potential well and the Ehrlich-Schwoebel barrier
Marta A. Chabowska, Hristina Popova, Magdalena A. ZaÅuska-Kotur
This study presents a comprehensive and innovative exploration of how the surface potential energy landscape influences meander formation. Using the Vicinal Cellular Automaton mode…
Surface Patterns Shaped by Additives in Crystals
M. A. Chabowska, M. A. ZaÅuska-Kotur
One technique for creating semiconductor crystals with new, desired properties involves replacing some atoms in the crystal lattice with additives - atoms of a different type. This…
