We find that for both materials hot spot interaction length coincides with the strip width, and the dependence of single and double-spot detection efficiencies on bias current are compatible with sufficiently large hot-spot size, approaching the strip width. %K NbN SSPD %K SNSPD %K MoSi %R 10.1088/1742-6596/1695/1/012146 %U https://iopscience.iop.org/article/10.1088/1742-6596/1695/1/012146 %U https://doi.org/10.1088/1742-6596/1695/1/012146 %P 012146 (1 to 3)
