(a)–(c) Left: Photoluminescence spectra of Mesas A, B and C, respectively. The arrows indicate peaks selected for photon correlation measurements on right. Right: Number of measured coincidences vs relative delay between two detectors. The time resolution (bin size) is . Total count rates on two detectors: (a) , (b) , (c) ; temperatures .
Left: Spectra measured at various excitation powers. Normalized powers are indicated. Right: Photon correlation measurements at selected powers.
Left: Spectra measured at various temperatures as indicated. At and , blinking behavior was observed, and two representative spectra are plotted. Right: Photon correlation measurements at selected temperatures.
