Morphological Transition: From Meanders to Mound Structures
Marta A. Chabowska, Hristina Popova, Magdalena A. ZaÅuska-Kotur
Mound formation on flat and miscut crystal surfaces exhibits distinct growth behaviors. While mound structures are the predominant feature on flat surfaces, miscut surfaces display…
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,…
Shape Selection in Nanopillar Formation
Marta A. Chabowska, Magdalena A. ZaÅuska-Kotur
Crystal growth processes produce a diverse array of surface formations, primarily distinguished by their geometric shapes. While some structures strictly adhere to the underlying c…
Twin Domains in 111 oriented {CdO/MgO} superlattices: homoepitaxy versus heteroepitaxy
Ewa Przeździecka, Aleksandra Wierzbicka, Abinash Adhikari +1
The structural properties of (111)-oriented {CdO/MgO} superlattice structures grown on c-sapphire and cubic MgO substrates have been studied by high resolution X-ray diffraction. T…
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…
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…
