The studies of energy levels and of recombination processes of single quantum dots, optically filled with up to four electron-hole pairs are the subject of this work. The dots used in the present experiments, formed out of the Ga(Al)As matrix, represent relatively strongly confined zero-dimensional systems, and display several, atomic-like s-, p-,. . . shells. Single dots can be easily selected in our structures as they exhibit an extremely low surface density. Experimental techniques applied in this work include the methods of single dot spectroscopy, polarization resolved techniques, application of magnetic fields and photon correlation measurements. Distinct, below- and above-dot-barrier laser excitation has been used for photoluminescen...
