Atomic force microscopy and polarised luminescence is used for studying interrelations between the surface morphology and the optical properties of multilayer (In,Ga)As/GaAs(100) nanostructures grown with molecular-beam epitaxy technique, which possess self-organised quantum dots and quantum wires. With increasing number of periods in the structure, aligning of the quantum dots in rows parallel to the crystal direction is observed. The improvement of lateral ordering correlates with increasing radiation anisotropy of the structure. A possible ordering mechanism is discussed.
Key words: quantum dot, quantum wire, polarization photoluminescence, AFM.
