Beschreibung:
  • We study dc-biased spin-transport in InAs two-stage spin-filter cascades. The cascades allow all-electrical generation and detection of spin-polarized currents in an all-semiconductor device. The application of a dc bias simplifies the interpretation of the experimental results, enhances the signal-to-noise ratio, and paves the way for more definite measurements in magnetic fields.
