FIG. 1.

(Color online) Schematic illustration of the hybrid spin injection device. IN, M1, SC, and FM denote insulator, low resistive metallic conductor, semiconductor, and ferromagnetic metal, respectively. Arrow shows current direction.

FIG. 2.

(Color online) Spin injection vs for different structures. (a) Basic FM-SC structure, (b) FM injector is patterned into pillars of smaller cross-sectional area, , and (c) an additional M1 layer inserted between patterned FM and SC. Arrow indicates the typical resistivity range for GaAs which can be varied by varying doping concentration.
