Abstract
Time-resolved excite-probe measurements were performed on GaAs multiple quantum wells to determine the spin relaxation time as a function of well width (L) at room temperature, and as a function of temperature in the range of 10 to 150 K. These studies suggest that the room temperature spin relaxation time follows an exponential well width dependence, indicating that at room temperature spin flip is dominated by a combination of the D'Yakonov-Perel and the Bir-Aronov-Pikus mechanisms. The low temperature results suggest that a different mechanism, the exchange interaction, is dominant at low temperatures.
