We have characterized self-assembled InAs quantum dots grown on the top of a single InGaAs/GaAs quantum well (QD's:QW) by measuring photoluminescence (PL) spectra as an effective technique. We have found that the linewidths of the PL peaks for the QD's:QW are narrower than that for the InAs quantum
Photocurrent spectroscopy is used to investigate the quantum-confined Stark shift, QCSS, of In 0.5 Ga 0.5 As/GaAs self-assembled quantum dots (QDs) grown on (100) and (311)B planes. An asymmetric dependence of the QCSS with respect to the direction of the electric field is observed in both cases. We
