Query: Spin-dependent resonant tunneling in symmetrical double-barrier
  structure   A theory of resonant spin-dependent tunneling has been developed for
symmetrical double-barrier structures grown of non-centrosymmetrical
semiconductors. The dependence of the tunneling transparency on the spin
orientation and the wave vector of electrons leads to (i) spin polarization of
the transmitted carriers in an in-plane electric field, (ii) generation of an
in-plane electric current under tunneling of spin-polarized carriers. These
effects originated from spin-orbit coupling-induced splitting of the resonant
level have been considered for double-barrier tunneling structures.
