FIG. 1.

(a) Time resolved right and left circular polarized components of the PL at 300 K and an excitation density of . The inset shows the corresponding degree of polarization . (b) Spin relaxation time versus electron density measured at 300 K. The inset shows the spin relaxation time in the low electron density regime for another data set. The linear density gradients are and for 300 and 350 K, respectively. The two dashed lines show accurate density dependence calculations beyond the motional narrowing regime.

FIG. 2.

(a) Measured spin-relaxation time linearly extrapolated to zero electron density (double logarithmic scale). The solid line is a fit to the experimental data proportional to . The dashed, red line is a numerical quantitative calculation according to Eq. (4). (b) Raw experimental (dots) and calculated (solid lines) at finite densities.
