Ultrafast extrinsic spin-Hall currents
E. Ya. Sherman, Ali Najmaie, H. M. van Driel +2
We consider the possibility of ultrafast extrinsic spin-Hall currents, generated by skew scattering following the optical injection of charge or pure spin currents. We propose a ph…
Generation of spin currents via Raman scattering
Ali Najmaie, E. Ya. Sherman, J. E. Sipe
We show theoretically that stimulated spin flip Raman scattering can be used to inject spin currents in doped semiconductors with spin split bands. A pure spin current, where oppos…
Spin current injection by intersubband transitions in quantum wells
E. Ya. Sherman, Ali Najmaie, J. E. Sipe
We show that a pure spin current can be injected in quantum wells by the absorption of linearly polarized infrared radiation, leading to transitions between subbands. The magnitude…
Pure spin current from one-photon absorption of linearly polarized light in noncentrosymmetric semiconductors
R. D. R. Bhat, F. Nastos, Ali Najmaie +1
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.…
