We present the first radiative lifetime measurements and magneto-photoluminescence results of excited states in InGaAs/GaAs semiconductor self-assembled quantum dots. By increasing the photo-excitation intensity, excited state interband transitions up to n = 5 can be observed in the emission spectru
We present a magneto-optical investigation of neutral and charged few-exciton complexes in individual In0:5Ga0:5As self-assembled quantum dots. The results reveal direct information regarding Coulomb interaction and correlation e ects in dots containing a controlled number of excess electrons (Ne =
