  5. 24. Polarization-resolved photoluminescence spectroscopy of III-nitride quantum dots

    Författare :Supaluck Amloy; Fredrik Karlsson; Per-Olof Holtz; Jørn M. Hvam; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : In this thesis, results from studies on (In)GaN quantum dots (QDs) are presented, including investigations of the structural, optical and electronic properties. The experimental studies were performed on GaN and InGaN QDs grown by molecular beam epitaxy, taking advantage of the Stranki-Krastanov growth mode for the GaN QD samples and the composition segregation for the InGaN QD samples.
