FIG. 1.

(Color online) Schematic illustration of the Si spin transport device used in this work (a) and associated conduction band diagram (b). The vertical structure (top to bottom) is undoped -Si. Spin-polarized hot electrons are injected by an emitter voltage from the tunnel junction cathode through the normal-metal anode base and into the conduction band of the thick undoped Si drift layer forming injected current . Detection on the other side is with spin-dependent hot-electron transport through the thin film. Our spin transport signal is the ballistic current transported into the conduction band of the collector .
