Filtering spin with tunnel-coupled electron wave guides
arXiv:cond-mat/0108373 · doi:10.1103/PhysRevB.65.140403
Abstract
We show how momentum-resolved tunneling between parallel electron wave guides can be used to observe and exploit lifting of spin degeneracy due to Rashba spin-orbit coupling. A device is proposed that achieves spin filtering without using ferromagnets or the Zeeman effect.
