Electrothermal simulation of superconducting nanowire avalanche photodetectors
Electrothermal simulation of superconducting nanowire avalanche photodetectors
We developed an electrothermal model of NbN superconducting nanowire avalanche photodetectors (SNAPs) on sapphire substrates. SNAPs are single-photon detectors consisting of the parallel connection of N superconducting nanowires. We extrapolated the physical constants of the model from experimental data and we simulated the time evolution of the device resistance, temperature …
