Mechanically-controlled spin-selective transport
arXiv:1403.5200 · doi:10.1103/PhysRevB.90.045401
Abstract
A device enabling mechanically-controlled spin and electric transport in mesoscopic structures is proposed. It is based on the transfer of electrons through weak links formed by suspended nanowires, on which the charge carriers experience a strong Rashba spin-orbit interaction that twists their spins. It is demonstrated that when the weak link bridges two magnetically-polarised electrodes, a significant spintro-voltaic effect takes place. Then, by monitoring the generated voltage one is able to measure electronic spins accumulated in the electrodes, induced e.g., by circularly-polarised light, or alternatively, the amount of spin twisting. Mechanically-tuning the device by bending the nanowire allows one to achieve full control over the spin orientations of the charge carriers.
