Spin-polarized transport in a quantum wire controlled by a magnetic field

ORAL

Abstract

We investigate the effects of $p^3$-dependent Dresselhaus spin-orbit interaction on the transport properties of a quantum wire. The particles are subjected to a magnetic field along, and an electrict field normal to the wire. The spin-orbit term leads to the spin-dependent renormalization of the mass of particles as well as the energy level splitting for different spins. This, in turn leads to spin-polarized tunneling transport controlled by the strength of the spin-orbit interaction and the magnetic and electric fields.
