The Frank–van der Merwe growth mechanism is observed in autoepitaxial systems and heteroepitaxial systems with very low lattice mismatch between the deposited material and the substrate. In this case a film grows by two-dimensional mechanism either by emergence of two-dimensional islands, or due to...
The harmonic interactions assumed in the Frank-van der Merwe model are replaced by Toda and Morse potentials in order to study the effect of anharmonicity on the equilibrium properties of thin epitaxial films. The extended model predicts the following. 1. (i) The misfit stability limits for pseu...
