Nonlinear dynamics of surface steps
Joachim Krug
TL;DR
This paper reviews recent theoretical research on the complex nonlinear dynamics of crystal surface steps, including electromigration-driven island motion and step bunching phenomena.
Contribution
It provides a comprehensive overview of recent advances in understanding nonlinear surface step dynamics, focusing on electromigration effects and step bunching mechanisms.
Findings
Electromigration causes complex island and void motion.
Step bunching occurs on vicinal surfaces under certain conditions.
Theoretical models explain observed surface phenomena.
Abstract
This is a review of recent theoretical work on complex dynamical behavior of steps on crystal surfaces. The first part of the article is devoted to the electromigration-driven motion of islands and voids, and the second part addresses step bunching on vicinal surfaces.
