... is completely suppressed in the case of growth on a sufficiently small area. These behaviors are in stark contrast to growth on an indefinitely large area, where the same model suggests that the minimum free energy configuration of systems beyond the wetting layer transition thickness is a single island atop...

... functionality and high performance. This article investigates growth on a topographically patterned substrate as a means to control the arrangement of islands. By taking free energy to consist of elastic energy and surface energy, minimum energy configurations are calculated for islands on a raised substrate...

... characterizing mechanical equilibrium. In particular, the equilibrium volume stress state of an epitaxial film as a function of the film thickness, surface free energies, and surface stresses is obtained. It is shown how this formalism can be used to determine the critical thickness for epitaxy. Contributed...

In particular, the free-energy function and the dissipation function become stochastic functionals whose scatter tends to decrease to zero as the material volume is increased. These functionals are linked...
