Irreversible Nucleation in Multilayer Growththe limits of mean-field theory (MFT). We show that MFT overestimates the correct result by a factor proportional to the number of times an adatom diffusing on the terrace visits an already visited lattice site. In this report we aim at giving a simple physical account of our results.

Coarsening Mechanisms in Surface Morphological Evolutionhanism is likely to be operative. Instead of a surface diffusion current driven by changes in surface curvature frequently assumed in phenomenological theories of coarsening, it appears that, even at high temperatures, coarsening is driven only by differences in curvature along contours of constant height.
