We report the fluorescence intermittency in self-assembled InP quantum dots studied by means of far field single dot spectroscopy. We found that the blinking efficiently occurs when the confined excitons are filled up to a certain level. Since blinking dots are observed in the vicinity of scratches,
Electronic coupling effects in self-assembled InAs quantum dots are investigated using capacitance and far-infrared (FIR) spectroscopy. Coupling between different dot-layers is studied using capacitance spectroscopy on samples with double-layers of vertically aligned quantum dots. A strong electrost
