Inhaltszusammenfassung

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.
