Superconducting nanowire single-photon detector made of ultrathin γ-Nb4N3 film for mid-infrared wavelengths

Yiming Pan et al.

Summary: This study demonstrates the potential of NbN-SNSPDs for use in MIR applications, especially for longer MIR wavelengths, by fabricating SNSPDs with gamma-Nb4N3 films instead of delta-NbN films. The dependence of the normalized detection efficiency on the bias current showed a clear trend towards a saturated plateau for wavelengths up to 2145 nm, indicating the feasibility of using gamma-Nb4N3 SNSPDs for longer MIR wavelengths.
