Keywords:spin, quantum well

The spin relaxation phenomenon in the quantum well is interesting in both basic physical properties and application.Elucidation of the mechanism of spin relaxation in Group III - V compound semiconductors is important for practical application of spintronic devices. It is expected to be applied to all - optical switching devices. We measured the well dependence of spin relaxation time in GaAs/Al0.3Ga0.7As single QW by time resolved pump and probe measurement.
