Abstract
In a recent paper [Phys. Rev. B 50, 3477 (1994)], P. Fratzl and O. Pen rose present the results of the Monte Carlo simulation of the spinodal decomposition problem (phase separation) using the vacancy dynamics m echanism. They observe that the t(1/3) growth regime is reached faster than when using the standard Kawasaki dynamics. In this Comment we pr ovide a simple explanation for the phenomenon based on the role of int erface diffusion, which they claim is irrelevant for the observed beha vior.
