22. We note that beyond 2 T external magnetic field, TRRF measurements similar to Fig. show a dragging of the transition due to dynamical nuclear spin polarization (Refs.). For the T B A measurements, we operate at nearly zero net nuclear spin polarization and all measurements are performed with constant laser frequency and gate voltage.
23. - 4 dependence (Ref.) was not observed for the magnetic field range of our experiments.
24. The deviation from the average value (obtained from measurements on 20 QDs) is likely to result in shorter T 1 times due to anisotropy enhanced spin-orbit coupling than similar measurements on a QD ensemble.
