Gate-Controlled Superconducting Proximity Effect in …

The superconducting proximity effect in single-walled carbon nanotubes connected to niobium electrodes was controlled with the use of nearby gates that tune the niobium-nanotube transparency. At 4.2 kelvin, when the transparency was tuned to be high, a dip in the low-bias differential resistance was observed, indicating a proximity effect mediated by Andreev reflection.

Physics - Get Wired for Superconductivity

As the team reports in the August Physical Review B, the wires are made from an unusual magnesium-carbon-nickel compound layered around a carbon fiber. Experiments with the wires strongly suggest that the compound is an “exotic” superconductor whose properties can’t be explained by the standard theory of superconductivity.
