摘要

During their relaxation to equilibrium, crystalline islands on misoriented (vicinal) substrates drift and deform. Our model indicates a generic and transient elongation perpendicular to the drift direction. The maximum elongation and the drift exhibit distinctive behaviors depending on the dominant energy contribution (interfa-cial energy, wetting potential, or elastic energy) and the dominant mass transport process (diffusion or attachment-detachment).
