Quantum dot formation during hetero-epitaxial growth of 3D islands in Stranski-Krastanow mode was described. The island size distribution function was shown to become narrower, and the dispersion decreased markedly for dislocation growth mechanism with subsequent separation of dislocations from the island base. Probable reasons for slowing down of Ostwald ripening were also considered.
