摘要

We comment on the conclusion by Teng et al (2009 J. Phys. D: Appl. Phys. 42 135111) that the Bir-Aronov-Pikus mechanism is more important than the D'yakonov-Perel' mechanism at a high carrier density in intrinsic bulk GaAs. We point out that the spin relaxation is solely from the D'yakonov-Perel' mechanism.
