Based on a parallel magnetoelectric nanostructure (MEMN) achieved by constructing a ferromagnetic stripe and a Schottky-metal stripe in a parallel configuration on the surface of an InAs/AlxIn1−xAs heterostructure, a temporal electron-spin splitter (TESS) was recently proposed. To control this spintronic device, δ-doping is introduced by atomic-layer doping technology. The dwell time of electrons in the parallel MEMN still depends on electron spins, even if δ-doping is included in the device. Both the magnitude and sign of electron-spin polarization in dwell time can be tuned by changing the δ-doping. A structurally controllable TESS can be obtained for spintronic device applications.
