Generation and Detection of Spin Currents in Silicon

Caption: The illustration shows the lateral device with the nonlocal detection, which was used to demonstrate the electrical injection, detection and modulation of spin current in silicon. A charge current of spin-polarized electrons follows the applied voltage and flows to the right, while a pure spin current flows to the left.
