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…
