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,…
Modelling crystallization: When the normal growth velocity depends on the supersaturation
V. V. Ivanov, C. Tielemann, K. Avramova +2
The crystallization proceeds by the advance of the crystal faces into the disordered phase at the expense of the supersaturation which is not sustained in our model. Using a conser…
Predicted universality class of step bunching found on DC-heated Si(111) surfaces
Alexey Kozlov, Alexander Samardak, Nikolay Chernousov +4
Concerted experimental and numerical studies of step bunching on vicinal crystal surfaces resulting from step-down electromigration of partially charged adatoms, confirmed the theo…
Bunch width versus macrostep height: A quantitative study of the effects of step-step repulsion
Hristina Popova, Filip Krzyżewski, Magdalena Załuska-Kotur +1
Bunching of steps at the surface of growing crystals can be induced by both directions of the driving force: step up and step down. The processes happen in different adatom concent…
Unstable dynamics of model vicinal crystal surfaces: Initial and intermediate stages
Filip Krzyżewski, Magdalena A. Załuska-Kotur, Anna Krasteva +2
We approach the old-standing problem of vicinal crystal surfaces destabilized by step-down and step step-up currents from a unified modelling viewpoint with focus on both the initi…
Step bunching with both directions of the current: Vicinal W(110) surfaces versus atomistic scale model
Olzat Toktarbaiuly, Victor Usov, Cormac Ó Coileáin +14
We report for the first time the observation of bunching of monoatomic steps on vicinal W(110) surfaces induced by step up or step down currents across the steps. Measurements reve…
