Magnetoelectric effects in semiconductor quantum wells with Rashba and Dresselhaus spin-orbit interaction

In the plane of a (001) quantum well with both Rashba and Dresselhaus spin-orbit interaction, a constant electric field as well as a surface acoustic wave are applied. The combined effect of both in-plane electric fields gives rise to a homogeneous out-of-plane spin polarization that exhibits a Hanle-like dependence on the constant electric field. In addition, a spin-mediated charge-current contribution is identified that is driven by the surface acoustic wave.
