Role of deposition noise in nanostructure formation: A theoretical investigation of quantum dots and quantum dotmolecules

Quantum dots (QDs) and quantum dot molecules (QDMs) are nanostructures that spontaneously self-assemble under different heteroepitaxial growth conditions to reduce the strain in the system. In the silicon–germanium system, QDs form when the rate of deposition is low, whereas QDMs form at higher depo...
