    • note
    • The width of the luminescence peak increases with temperature from 3.5 to 12 nm. For temperatures above 100 K we used the low energy side of the PL spectrum to determine spin polarization (peak to lower energetic half of the hh transition). A possible contribution of the broadened lh transition above 50 K can lower the degree of PL polarization but does not obscure spin relaxation data, because the ratio of hh and lh emission exhibits no transient change. Holes are at elevated temperatures almost instantly in thermal equilibrium.

    • The spin dephasing times for B = 0 in Fig. 2 at low temperatures are deduced from the best exponential fit in the time interval between 0 and 1.8 ns.
