  • Fast spin-polarized electron source
    Patent number: 11011337
    Abstract: Systems and methods for obtaining fast, spin-polarized electrons from an edge or tip or cusp of a target material, e.g., a sharp GaAs crystal edge or tip, or a cusp, which naturally incorporates optical reversibility. A source of fast spin-polarized electrons may include a target material including a sharp tip or tip portion or a sharp edge or a cusp, the tip or tip portion including at least two intersecting edges, and a pulsed light source configured to emit one or more light pulses focused on the sharp tip or tip portion or the sharp edge or the cusp to thereby induce emission of spin-polarized electrons from the sharp tip or tip portion or the sharp edge or the cusp of the target material.
    Type: Grant
