摘要

This work presents the results of the growth, structural characterization and magneto-photoluminescence spectroscopy measurements of GaAs/AlGaAs/InP/GaInP2 quantum well-quantum dot structures. We demonstrate that GaAs/AlGaAs QDs in these structures are formed above InP/GaInP2 QDs. This allows us to measure the internal magnetic field in the InP/GaInP2 QD by monitoring the Zeeman splitting of the excitonic transition in the GaAs/AlGaAs QD.
