Scaling laws for step bunching on vicinal surfaces: the role of the dynamical and chemical effects
Lucas Benoit--Maréchal, Michel E. Jabbour, Nicolas Triantafyllidis
We study the evolution of step bunches on vicinal surfaces using a thermodynamically consistent step-flow model that (i) circumvents the quasistatic approximation that prevails in…

Revisiting step instabilities on crystal surfaces. Part II: General theory
L. Guin, M. E. Jabbour, L. Shaabani-Ardali +1
The quasistatic approximation is a useful but questionable simplification for analyzing step instabilities during the growth/evaporation of vicinal surfaces. Using this approximati…

Revisiting step instabilities on crystal surfaces. Part I: The quasistatic approximation
L. Guin, M. E. Jabbour, N. Triantafyllidis
Epitaxial growth on a surface vicinal to a high-symmetry crystallographic plane occurs through the propagation of atomic steps, a process called step-flow growth. In some instances…
