Step Bunching: Influence of Impurities and Solution Flow



A A. Chernov, P G. Vekilov, Sam R. Coriell, B T. Murray, Geoffrey B. McFadden


Step bunching results in striations even at relatively early stages of its development and in inclusions of mother liquor at the later stages. Therefore, eliminating step bunching is crucial for high crystal perfection. The nature of step bunching generated at the corners and edges and by dislocation step sources, as well as the also relative importance and interrelations between various mechanisms is not clear, both from experimental and theoretical standpoints. Furthermore, several laws controlling the evolution of existing step bunches have been suggested, though unambiguous conclusions are still missing. Addressing these issues is the major goal of the present paper.
