We propose to separate electron-spins by transmission time for electrons across a semiconductor microstructure. By calculating dwell time of electrons in a realistic magnetic microstructure, transmission time is found to be spin related, electron spins are, therefore, separated in time dimension. Besides, both magnitude and sign of spin-polarized dwell time can be manipulated by an applied voltage, which may give rise to an electrically-controllable temporal spin splitter for spintronics device applications.

磁微结构中电子的时域自旋极化

我们建议通过电子在半导体微结构上的传输时间来分离电子自旋。通过计算现实磁性微观结构中电子的停留时间，发现传输时间与自旋有关，因此电子自旋在时间维度上是分开的。此外，自旋极化的停留时间的大小和符号都可以通过施加电压来控制，这可能会为自旋电子器件的应用带来电控的临时自旋分束器。
