摘要
By studying the time and spatial evolution of a spin-polarized pulse in n-type semiconductor quantum wells, we highlight the importance of the off-diagonal spin coherence in spin diffusion and transport. Spin oscillations and spin polarization reverse along the direction of spin diffusion in the absence of the applied magnetic field are predicted from our investigation.
