FIG. 1.

Measured PL signal from a single quantum well as a function of temperature, with the transmission through also shown. The inset is a plot of the energy at which the maximum PL signal occurs, together with the band gap of and estimated transition energies, as a function of temperature. The dotted lines are guides to the eye only.

FIG. 2.

Temperature dependence of the integrated PL signal from a single quantum well. The dotted line is a guide to the eye only. The same experimental data are shown in an Arrehenius plot in the inset, with a linear least squares fit to the data at high temperatures.

Image of FIG. 3.
FIG. 3.

Measured PL signal from a single quantum well as a function of incident laser power. The integrated PL signal from the “peak” and “tail” is plotted as a function of incident laser power , on log scales, in the inset. The dotted lines are linear least squares fits to the data.
