Figure 4. The coherent bundlelike surface nucleus model and its crystal growth rate behavior.

(a) Coherent nucleus of length l, width a, and monomolecular layer thickness b₀ on substrate crystal. Heavy arrow marked G indicates direction of crystal growth.

(b) The logarithm of growth rate versus temperature, — — — — log G versus T if effect of jump rate is small; ▬▬ behavior where jump rate lowers log G causing maximum to appear in log G versus T;…. possible effect of interference with growth by excess nucleation in surrounding medium (cf. fig. 1(a)).
