摘要

We demonstrate the electrical control of the electron spin relaxation in GaAs/AlGaAs multiple quantum wells grown on (111)A substrate. By embedding the wells in a NIP structure, the application of an external bias yields a large increase of the electron spin relaxation time due to the compensation of the Dresselhaus spin-splitting by the Rashba one. Depending on the direction of the applied electric field, the electron spin relaxation can be slowed-down or sped-up. It can be tuned by a factor 50 at 75 K and still by a factor 2 at 250 K.
