Spectroscopy of quantum Hall edge channel transfer. a 2D-colour plot of the current through the Detector QD for varying Detector QD (x-axis) and Emitter QD plunger gate voltage (y-axis). The encircled numbers refer to the energetic points mentioned in the text and are explained in detail in the Supplementary Note 1. The signal is plotted on a logarithmic colour scale preserving the direction of electron tunnelling in the colour code. b Calculated current through the Detector QD for the experimental situation depicted in (a). Γ is the tunnelling rate through the QD. c–e schematic description of the electron scattering processes involved in the transfer. f Diagram corresponding to the process in (e), generating current in the triangle ①–②–④
