Abstract :
We have demonstrated the injection, modulation and detection of pure spin diffusion current in silicon in a lateral transport geometry compatible with existing device design, fabrication and scaling. This approach injects spin-polarized electrons near the silicon conduction band edge with near unity conversion efficiency and low bias voltages (~ 2 eV) compatible with CMOS technology.
