我们研究了面内电场对GaAs量子阱中自旋漂移的影响。漂移自旋的克尔旋转图像显示，无论输运方向如何，自旋进动波长都随着漂移速度的增加而增加。建立了一个具有受热电子分布的漂移自旋的模型，该模型表明面内电场增强了源于立方Dresselhaus自旋-轨道相互作用的有效磁场分量。
We investigated the effect of an in-plane electric field on drifting spins in a GaAs quantum well. Kerr rotation images of the drifting spins revealed that the spin precession wavelength increases with increasing drift velocity regardless of the transport direction. A model developed for drifting spins with a heated electron distribution suggests that the in-plane electric field enhances the effective magnetic field component originating from the cubic Dresselhaus spin-orbit interaction.
