| 英文摘要 | We theoretically investigate the electron transport and spin polarization of two coupled quantum wells with dresselhaus spin-orbit interaction. in analogy with the optical dual-channel directional coupler, the resonant tunneling effect is treated by the coupled-mode equations. we demonstrate that spin-up and -down electrons can be completely separated from each other for the system with an appropriate system geometry and a controllable barrier. our result provides a new approach to construct spin-switching devices without containing any magnetic materials or applying a magnetic field.
