Abstract

Microstructural evolution in systems containing strained islands (coherent, incoherent of both) is investigated. The growth rate of an individual island coarsening in an ensemble of strained islands is obtained by including elastic effects on surface diffusion of adatoms to and the equilibrium solubility of strained islands. For strained islands growing on a quasi-rigid substrate, coherent islands grow more slowly than incoherent islands of the same radius. Consequently, the island growth rate accelerates at the coherent to incoherent transition. the model agrees with recent experimental observations in Ge/Si(100) heteroepitaxy.
