Paper Abstract

We have studied magneto-oscillations of the tunnelling current through a quantum well (QW) incorporating InAs self-assembled quantum dots in magnetic fields up to 28 T applied normal to the QW plane. We find evidence for the strong modification of the Landau levels in the host GaAs quantum well in the presence of dots embedded at the center of the well, which we attribute to electron-electron interactions.
