    • Due to a slow drift of the device parameters the fine structure in consecutive traces did not fully reproduce. This prevented a detailed test of the symmetry of the magnetoconductance. However, the amplitude of the oscillations as well as their period were approximately the same for both field orientations.

    • van Loosdrecht et al. (Ref. 7) have observed a large asymmetry in the amplitude of the oscillations in forward and reverse fields. Also, two sets of oscillations with slightly different periods were observed, which were attributed to spin splitting. In our device the spin splitting is fully resolved, as a result of which we only expect and observe a single set of oscillations.

    • The Fermi energy is approx 9 meV, which means that a large number of 0D states are occupied.

    • At the 2DEG boundary the electrostatic potential changes by an amount EF/e (approx 9 mV) in a depletion region which is about 300 nm wide. This gives a typical field strength E approx 3 times 104 V/m.

    • In a fixed magnetic field (2.5 T) oscillations in GD are observed with a period approx 1 mV, when the voltage on both gate pairs is swept. From the dependence of this period on the gate voltage we obtained an estimate for the edge channel radius: r approx 350 nm.
