Abstract

In most papers concerning theory of crystal growth the distance between turns of the growth spiral (step distance) is described by Cabrera and Levine approximation. However, other approximations of this distance are proposed in literature. The effect of the applied step distance approximations on the dependences of growth units concentration and crystal growth rate versus supersaturation are analyzed in this paper. The results of calculations show that the Cabrera and Levine approximation may be used for very low supersaturations only.
