Spintronics breakthrough at NRL

December 5, 2007

Scientists at the Naval Research Laboratory are claiming to have made a breakthrough in spintronics. From the press release:

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.

I’m not a spintronics expert, but evidently the breakthrough is seeing the effect in silicon, rather than the III-V semiconductors.
