TL;DR: In this paper, the authors show for a coherent epitaxy that three conditions are necessary and sufficient to rationalize the problem: (i) the perfect wetting condition of Bauer's criterion expressed in terms of long range forces, (ii) an elastic misfit energy of the so produced layers, and (iii) elastic striction energy induced in the substrate by appearing islands.
