Description
We report the low-temperature study of very thin NbxSi1-x films that are used in various systems for astrophysical detection with bolometers. We have decreased the thin film thicknesses from 60nm down to 12.5nm and shown that the sensitivity gain due to lowering the heat capacity is not to the detriment of the electron-phonon coupling or to noise characteristics. On the superconducting side, we show that, at small thicknesses, the critical temperature and the normal resistance can be adjusted by tuning the thickness and the composition of the films
