Abstract
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, a n infinite elastic self-interaction force on a curved step. The merger of i mpinging islands and the dynamics of step bunching in a step train are stud ied numerically using a two-dimensional version of this model. (C) 1999 Els evier Science S.A.
