Optically probing the detection mechanism in a molybdenum silicide superconducting nanowire single-photon detector
We experimentally investigate the detection mechanism in a meandered molybdenum silicide superconducting nanowire single-photon detector by characterising the detection probability as a function of bias current in the wavelength range of 750–2050 nm. Contrary to some previous observations on niobium nitride or tungsten silicide detectors, we find that the energy-current …
