a A 3D illustration of the device. The two quantum dots (QDL and QDR), and the region hosting ABSs are indicated. For clarity, the gate-dielectric layers are not shown. b False-color scanning electron micrograph of Device 1, including a schematic of the circuit diagram for three-terminal measurements. Tunneling spectroscopy measurements showing (c) local conductance GRR and (d) non-local conductance GLR as a function of the ABS gate voltage VABS and right bias voltage VR. Coulomb diamonds of the QDs are measured for (e) QDL and (f) QDR.
