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…
Step bunching and macrostep formation in 1D atomistic scale model of unstable vicinal crystal growth
F. Krzyżewski, M. Załuska-Kotur, A. Krasteva +2
We devise a new 1D atomistic scale model of vicinal growth based on Cellular Automaton. In it the step motion is realized by executing the automaton rule prescribing how adatoms in…
Double step structure and meandering due to the many body interaction at GaN(0001) surface in N-rich conditions
Magdalena A. Załuska-Kotur, Filip Krzyżewski, Stanisław Krukowski
Growth of gallium nitride on GaN(0001) surface is modeled by Monte Carlo method. Simulated growth is conducted in N-rich conditions, hence it is controlled by Ga atoms surface diff…
Diffusion of atoms interacting by long-range and oscillating forces
Filip Krzyżewski, Magdalena A. Załuska-Kotur
Collective diffusion coefficient in a one dimensional lattice gas adsorbate is calculated using variational approach. Particles interact via either a long-range, or a long range el…
