Scientists generate, modulate, and electrically detect pure spin currents in silicon

Scientists generate, modulate, and electrically detect pure spin currents in silicon from PhysOrg.com

Scientists at the Naval Research Laboratory (NRL) have generated, modulated and electrically detected a pure spin current in silicon, the semiconductor used most widely in the electronic device industry. Magnetic contacts on the surface of an n-type silicon layer enable generation of a spin current which flows separately from a charge current.
