We have investigated the spin relaxation process of electron at room temperature in nominally undoped GaAs/AlGaAs multiple-quantum wells. The spin relaxation times are measured for different well thicknesses using time-resolved polarization absorption measurement. The spin relaxation time τs, is found to depend on the electron confined energy E1e, according to τs∝E1e-2.2, showing that the main spin relaxation mechanism at room temperature is the D'yakonov-Perel' interaction.
