Abstract
The electron spin relaxation of InGaAs/InP multiple-quantum wells is investigated at room temperature using time-resolved polarization-dependent absorption measurements. The spin relaxation time is dependent on the quantum confined energy, E 1e, according to τs∝E 1e -1. The dependence differs from that of the D'yakonov-Perel' interaction, which governs the spin relaxation of GaAs quantum wells at room temperature, and suggests the possibility of the existence of an additional spin relaxation mechanism.Keywords
