AbstractResults 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 in magnetic field up to . 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.
