New Publication: “Large-Area Superconducting Nanowire Single-Photon Detectors for Operation at Wavelengths up to 7.4 μm”
The optimization of superconducting thin-films has pushed the sensitivity of superconducting nanowire single-photon detectors (SNSPDs) to the mid-infrared (mid-IR). Earlier demonstrations have shown that straight tungsten silicide nanowires can achieve... Read more >>

New paper: “Universal scaling of the critical temperature for thin films near the superconducting-to-insulating transition” accepted to Phys. Rev. B
[preprint] [supp. info.] We reported that the superconducting properties scale universally close to the superconducting-to-insulating transition in thin films. This universal behavior was found useful not only for the fundamental... Read more >>
