Oscillating gate voltages (top) and the associated travelling-wave potential in the quantum well (bottom) for the conventional four-phase conveyor. Gates can be divided into four sets (numbered 1–4), and the colour above each gate corresponds to the phase of the applied sine signal. A indicates the amplitude of the voltage signal, and the lever arm α expresses the conversion of gate voltage to dot potential. In the experiment, two different amplitudes are applied to gates in separate fabrication layers to compensate for the difference in lever arm (not shown in the figure for simplicity).
