Nonlinear spin Hall effect in GaAs (110) quantum wells

Year: 2011
Type: article
Abstract: We consider a stationary spin current in a (110)-oriented GaAs-based symmetric quantum well due to a nonlinear response to an external periodic electric field. The model assumed includes the Dresselhaus spin-orbit interaction and the random Rashba spin-orbit coupling. The Dresselhaus term is uniform in the quantum well plane and gives rise to spin splitting of the electron band. The external electric field of frequency $\ensuremath{\omega}$---in the presence of random Rashba coupling---leads to virtual spin-flip transitions between spin subbands, generating a stationary pure spin current proportional to the square of the field amplitude.
