Zusammenfassung:
We report on high-excitation photoluminescence (PL) measurements of an
ensemble of InAs/GaAs self-assembled quantum dots with large
inter-shell spacing (75 meV) in magnetic fields up to 73 T. The PL
spectra show a complex picture of levels splitting and crossings. A
simple two-band single-particle model provides a good approximation to
explain the observed magneto-PL spectra. (C) 2003 Elsevier B.V. All
