Abstract

We have studied the mechanism of energy relaxation and resistive state formation after absorption of a single photon for different wavelengths and materials of single photon detectors. Our results are in good agreement with the hot spot model.

Key words: superconducting single photon detectors / optical and IR wavelength radiation
