Molecular beam epitaxy (MBE) grown In0.5Ga0.5As/GaAs multilayer structures with quantum dots chains (QDs), obtained under different growth conditions, were investigated by high-resolution X-ray diffractometry (HRXRD) and AFM. It was determined that self-organized epitaxial growth of In0.5Ga0.5As/GaAs can lead to the formation of three-dimensional quantum-dot crystals with triclinic (distorted cubic) unit cell. The mechanisms of QDs ordering in dependence on As flux are analyzed.
