  3. 17. Spin Properties in InAs/GaAs Quantum Dot based Nanostructures

    Författare :Jan Beyer; Weimin Chen; Irina Buyanova; Hongqi Xu; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Semiconductor quantum dots (QDs) are a promising building block of future spin-functional devices for applications in spintronics and quantum information processing. Essential to the realization of such devices is our ability to create a desired spin orientation of charge carriers (electrons and holes), typically via injection of spin polarized carriers from other parts of the QD structures.
