Abstract:
In this work, we demonstrate the possibility of using a diluted magnetic semiconductor GaAs:Fe as a ferromagnetic injector in a spin light-emitting diode based on a GaAs/InGaAs quantum well heterostructure. It is shown that in such a device it is possible to observe partially circularly polarized electroluminescence at room temperature.
Keywords:spin light-emitting diodes, diluted magnetic semiconductors, A$^3$B$^5$ semiconductors, spin injection.
