Time-resolved spectroscopy of a three-terminal semiconductor structure for electrical spin-storage and read-out — •Helge Wurst, Andreas Merz, Johannes Zeller, Robert Schittny, Benjamin Wolter, Christoph Krämmer, Heinz Kalt, and Michael Hetterich — Karlsruhe Institute of Technology (KIT) and DFG Center for Funtional Nanostructures (CFN), 76131 Karlsruhe, Germany

In recent years, spin light-emitting diodes have become well-established devices in the spintronics community. In this contribution, we present time-resolved measurements performed at a transistor-like structure aiming at spin-injection, prolonged spin storage and spin-readout with all of these processes controlled individually and all-electrically. This structure consists of a diluted magneti semiconductor as spin-injector and quantum dots which are selectively loaded with electrons and holes, respectively.
