説明:

(abstract)

Employing time-resolved Kerr rotation microscopy, we demonstrate electrical control over the orientation of the persistent spin helix in a double GaAs quantum well structure equipped with independent front and back gates. We map spin polarization patterns under varying gate voltages and show that coordinated tuning of two gates enables switching between two orthogonal persistent spin helix (PSH) orientations.
