(a) AFM map of the sample surface which gives the areal density of the buried QDs. (b) Two macro-PL spectra at two different excitation powers (, red line and , black line). (c) PL time resolved decay obtained at the energy of 1.65 eV.

FIG. 2.

(a) Spatially and spectrally resolved PL maps. (b) micro-PL spectra at different excitation powers. (c) PL intensity of the X and XX lines as a function of the excitation power compared with the Poissonian fits.

Image of FIG. 3.
FIG. 3.

(a) Comparison between the macro-PL spectrum and the histogram of the X spectral lines observed in micro-PL spectra. (b) Distribution of the FWHM of the excitonic lines as a function of different emission energies.
