AbstractSelf-assembled AI36Ino.As/AIo33Gao.67As quantum dots have been studied by single dot photoluminescence spectroscopy at T= 1.5 K. Emission from the biexciton state is observed, for which we find a binding energy of 5 meV, also, larger multi-exciton complexes are observed at higher excitation intensities. These artificial atoms are found to have an intersublevel spacing of7O meV. In magnetic field, we observe Zeeman splitting ofthe exciton and biexciton spectral lines.
