中文摘要	we investigate the spin relaxation time of holes in an ultrathin neutral inas monolayer (1.5 ml) and compare with that of electrons, using polarization-dependent time-resolved photoluminescence (trpl) experiments. with excitation energies above the gaas gap, we observe a rather slow relaxation of holes (tau(1h) = 196 +/- 17 ps) that is in the magnitude similar to electrons (tau(1e) = 354 +/- 32 ps) in this ultrathin sample. the results are in good agreement with earlier theoretical prediction, and the phonon scattering due to spin-orbit coupling is realized to play a dominant role in the carrier spin kinetics.
