Zero-field electron transfer. Current through the Emitter (red) and Detector (blue) QD as a function of Detector plunger gate voltage in the absence of a perpendicular magnetic field (B = 0 T). The black dashed line indicates the background contribution of the Detector QD current due to an experimentally unavoidable slight misalignment between μRes and μDrain. The current through the Emitter QD stays constant for varying Detector QD chemical potential. The current through the Emitter QD shows both elastic and inelastic contributions. The insets show the schematic level alignment of the respective configurations
