Scientists have built a narrow constriction in bilayer graphene that can be turned into different numbers of transport channels by adjusting a gate voltage. When the device is cooled below the critical temperature of a nearby aluminium electrode, the conductance through the constriction grows inside a small voltage window. The size of the enhancement – up to 1.4 times the resistance‐free value – is largest when the gate voltage puts the point contact on a conductance plateau, and it drops between plateaus. From the width of the conductance window, which extends about 140 µeV, the researchers infer a proximity‑induced superconducting gap of similar size to that of the aluminium film (≈155 µeV). The data also reveal that the enhancement survives in magnetic fields that are parallel to the graphene plane up to the aluminium critical field, whereas it is weakened almost linearly by perpendicular fields, suggesting vortex entry in the aluminium film. These results demonstrate that mode‑dependent Andreev reflection can be probed with a gate‑controlled graphene constriction and that the induced superconductivity is robust in high‑field geometries, a key step toward graphene‑based superconducting devices.
