FIG. 1.

(Color online) QD density, as measured from AFM images plotted as a function of InAs deposition rate. The solid line is a guide for the eyes. Inset: AFM images of 2.1 ML InAs deposited at the following growth rates: (a) , (b) , (c) , (d) .

FIG. 2.

Evolution of PL emission wavelength as a function of InAs growth rate. The solid line is a guide for the eyes. Inset: PL spectra at 10 K and RT of 2.1 ML InAs QDs grown at with a 5 nm thick capping layer.

Image of FIG. 3.
FIG. 3.

PL spectra of QDs embedded in a microcavity ( diameter mesa) at different excitation powers. Peaks X and XX are attributed to exciton and biexciton emission.

Image of FIG. 4.
FIG. 4.

Integrated intensities of X and XX peaks as a function of the laser excitation power, under continuous-wave excitation. Solid (dashed) line shows the fitted power dependence of X (XX) intensity and the inset reports the dependence of the XX-PL intensity versus the X-PL intensity in log-log scale.

FIG. 5.

PL spectra of a single QD in a microcavity ( diameter mesa) at different temperatures (excitation power , pump wavelength ).
