Abstract
The electron energy bands in a semiconductor quantum wire in general are expected to show a wave vector dependent spin splitting with terms proportional to k3. We show that the wave vector dependence gives rise to a strong asymmetry of the electron-electron pair scattering with respect to the spin subbands. We show that one consequence of this asymmetry is a new physical effect: Spontaneous Spin Polarization. An electron spin polarization device based on this effect is proposed. The operating principle is explained and limits are discussed.
