A three-dimensional model of step flow mediated crystal growth under the combined influences of stress and diffusion


This paper presents a three-dimensional model of step flow mediated crystal growth which carefully accounts for both stress and terrace diffusion. Two regularization schemes are proposed to deal with the primary difficulty, an infinite elastic self-interaction force on a curved step. The merger of impinging islands and the dynamics of step bunching in a step train are studied numerically using a two-dimensional version of this model.
