摘要：

We show that one-photon absorption of linearly polarized light should produce pure spin currents in noncentrosymmetric semiconductors, including even bulk GaAs. We present 14x14 k center dot p model calculations of the effect in GaAs, including strain, and pseudopotential calculations of the effect in wurtzite CdSe.
