The kinetics of monoatomic steps in diffusion-controlled crystal growth and evaporation processes are investigated analytically using a Green's function approach. Integro-differential equations of motion for the steps are derived; a systematic linear stability analysis is carried out treating simultaneously perturbations both along and perpendicular to the steps. Morphological fluctuations of steadily moving steps in response to ambient thermodynamic noises are also studied within a general…

Multiscale Modeling of Epitaxial Growth: From Discrete-Continuum to Continuum Equations
Imposed by the crystal lattice, at the surface of a crystal, there exist atomic steps, which separate exposed lattice planes that differ in height by a single lattice spacing. These steps are
Phase field model for the dynamics of steps and islands on crystal surfaces
Surface stress and lattice strain are the essential factors on the self-organization of a surface, because they affect remarkably adatom diffusion on surfaces and at step edges and induce the elastic

Morphological instability of steps during crystal growth from solution flow
It is shown that a step moving to meet a solution flow can be unstable against lateral perturbations. The instability of long-wavelength perturbations occurs at values of the solution flow intensity
Surface step dynamics
Publisher Summary Atomic steps on a facet or on a vicinal face of a crystal play a crucial role in the growth of a faceted crystal. To understand the behavior of steps at a mesoscopic level, two
