  • Title: Universal intrinsic spin Hall effect.
    Author: Sinova J, Culcer D, Niu Q, Sinitsyn NA, Jungwirth T, MacDonald AH.
    Journal: Phys Rev Lett; 2004 Mar 26; 92(12):126603. PubMed ID: 15089695.
    Abstract:
    We describe a new effect in semiconductor spintronics that leads to dissipationless spin currents in paramagnetic spin-orbit coupled systems. We argue that in a high-mobility two-dimensional electron system with substantial Rashba spin-orbit coupling, a spin current that flows perpendicular to the charge current is intrinsic. In the usual case where both spin-orbit split bands are occupied, the intrinsic spin-Hall conductivity has a universal value for zero quasiparticle spectral broadening.
