Dynamics of crystal steps

Abstract In this article, we wish to point out some of the recent advances in the study of step dynamics on crystal surfaces. We will first list some approaches to steps dynamics, based on irreversible thermodynamics, kinetic roughening concepts, and mass transport mechanisms. In a second part, we shall analyze step motion coupled to the diffusion of mobile atoms on terraces. A special focus will be given on pattern formation on vicinal surfaces and two-dimensional islands. Finally, we will report on the consequences of elastic and electronic relaxation on the dynamics of steps and adatoms. To cite this article: O. Pierre-Louis, C. R. Physique 6 (2005).
