Nanomechanical Spin-Polarizer
arXiv:0711.4430 · doi:10.1103/PhysRevLett.101.036401
Abstract
Torsional oscillations of a free-standing semiconductor beam are shown to cause spin-dependent oscillating potentials that spin-polarize an applied charge current in the presence of intentional or disorder scattering potentials. We propose several realizations of mechanical spin generators and manipulators based on this piezo-spintronic effect.
