摘要：
Polarization-resolved, subpicosecond pump-probe measurements at a wavelength of 3.43 mu m are used to determine the electron spin relaxation time T-1 in bulk InAs at room temperature. The measured T-1 of 19 +/- 4 ps is in excellent agreement with the theoretical value of 21 ps, which is obtained from a nonperturbative calculation based on the D'yakonov-Perel' mechanism of precessional spin relaxation [M. I. D'yakonov and V. I. Perel', Sov. Phys. JETP 38, 177 (1974)]. (C) 2000 American Institute of Physics. [S0003-6951(00)03735-9].
