TL;DR: In this article , the properties of the fabricated detector, such as efficiency, timing resolution, and energy sensitivity, were investigated, based on the NbTiN and MoSi deposition parameters.

TL;DR: In this article , the authors presented 12nm thick superconducting nanowire single-photon detectors (SNSPDs) that showed an increase of system detection efficiency from less than 0.01% to 55% and saturating internal detection efficiency at 4K after irradiation with helium ions.

TL;DR: In this paper , the impact of the substrate material on SNSPD performance was investigated and the fundamental interrelation of the resulting voltage pulse properties, such as pulse height, rise time and timing jitter, and their dependence on the applied bias current was discussed.

TL;DR: Superconducting nanowire single-photon detectors are key components for quantum technologies. They provide low timing jitter, dark counts and dead time. This work explores various engineering aspects of SNSPDs including stoichiometry, helium ion irradiation and embedding in an optical cavity. The results demonstrate significant improvements in detector performance.
