摘要：
The results of the dependence of the tapering angle θ and the micromorphology of tapered faces on the concentration of Fe3+ and Cr3+ impurities at various supersaturations are presented and discussed. The kinetic data on tapering angle are analysed by considering the adsorption of impurity species at kinks and steps on a surface and calculating the corresponding energy of adsorption. The analysis suggests that adsorption of both Fe3+ and Cr3+ impurities takes place at kink sites on {100} faces. © 1990, Elsevier Science Publishers B.V.. All rights reserved.
