Abstract
Highly sensitive, broadly tunable detectors are needed for future sensing applications and quantum information systems. A promising material for these challenges comprises stacked graphene sheets having a “magic” twist angle between their in-plane symmetry axes. This material displays superconductivity with a ~ 2 K transition temperature. We investigate a proposed design for a fast and sensitive detector of THz and mm-waves based on antenna-coupled magic-angle-twist-graphene Josephson junctions. The considered non-bolometric detection mechanism depends on the decrease in the maximum zero-voltage DC current when AC current is driven through the junction. Finite element electrodynamic simulations favor the bowtie over log-periodic, square spiral, and Archimedean spiral antenna designs. Responsivity, noise-equivalent-power, and the prospects for single-photon detection are estimated.
Graphical abstract
Graphene sheets stacked with “magic” twist angle display superconductivity. Josephson junctions can be created by selective gating. We investigate a non-bolometric detection mechanism that promises simultaneous high speed and sensitivity, with potential application to quantum cryptography in the 5G band. A noise-equivalent-photon flux of 1 photon every 6 ns is the projected sensitivity for THz and mm-waves.
