Caption: Electrical injection of spin-polarized electrons into silicon has proven elusive, but is essential to enable the use of spin angular momentum as an alternative state variable in future silicon electronics. Efficient injection of spin-polarized electrons from the iron/aluminum oxide tunnel barrier contact is confirmed by the emission of circularly polarized electroluminescence from the silicon. The illustration shows the surface-emitting LEDs used in this study.
