摘要

Results of photoluminescence excitation (PLE) measurements of quantum dots (QDs) in high magnetic field are presented in this work. A structure with a single layer of InAs/GaAs QDs of a relatively small inter-level spacing and inhomogeneous broadening has been investigated at T=4.2 K in magnetic field up to 28 T. It has been found that the PLE spectrum at zero magnetic field, with detection energy set at the ground state (s-shell) of the QDs, is dominated by two features. These have been attributed to absorption in the QDs p- and d-shell, respectively. The peaks split in magnetic field following the pattern of the Fock-Darwin potential and features, attributed to the lowest Landau level in the QDs can be observed in high magnetic field.
