Phys. Rev. Lett. 94, 096603 (2005) [4 pages]Pure Spin Current from One-Photon Absorption of Linearly Polarized Light in Noncentrosymmetric SemiconductorsReceived 2 April 2004; published 11 March 2005 We show that one-photon absorption of linearly polarized light should produce pure spin currents in noncentrosymmetric semiconductors, including even bulk GaAs. We present 14×14 k·p model calculations of the effect in GaAs, including strain, and pseudopotential calculations of the effect in wurtzite CdSe. © 2005 The American Physical Society URL:
