Time Scaling Relations for Step Bunches from Models with Step-Step Attractions (B1-Type Models)
Anna Krasteva, Noriko Akutsu, Vesselin Tonchev
The step bunching instability is studied in three models of step motion defined in terms of ordinary differential equations (ODE). The source of instability in these models is step…

Unstable vicinal crystal growth from cellular automata
Anna Krasteva, Hristina Popova, Filip Krzyzewski +2
In order to study the unstable step motion on vicinal crystal surfaces we devise vicinal Cellular Automata. Each cell from the colony has value equal to its height in the vicinal,…
