Basic design of a three-terminal semiconductor structure for electrical spin-storage and read-out — •Johannes Zeller, Rouven Diehm, Pablo Asshoff, Andreas Merz, Heinz Kalt, and Michael Hetterich — Karlsruhe Institute of Technology (KIT)

In recent years, spin light-emitting diodes have become well-established devices in the spintronics community. In this contribution, we discuss a novel structure design allowing for spin-injection, prolonged spin-storage and spin-readout with all of these processes controlled individually and all-electrically. This structure consists of a diluted magnetic semiconductor as spin-injector and quantum dots which are selectively loaded with either electrons or holes.
