| 英文摘要 | We have investigated the electron spin relaxation in undoped InGaAsP grown on an InP substrate. Time-resolved spin-dependent pump and probe reflection measurements revealed a spin relaxation behavior between 10 and 300K. We have observed the electron spin relaxation times of 980ps at 10K and 95ps at room temperature. The observed presence of the carrier density dependence and the weak temperature dependence of spin relaxation time imply that the Bir-Aronov-Pikus (BAP) process is effective at 10-30K. At 100-300K, the observed presence of the temperature dependence and the absence of the carrier density dependence of spin relaxation time indicate that the D'yakonov-Perel' (DP) and Elliott-Yafet (EY) processes are effective.
