The observed electron-phonon cooling times vary from 160 ns at 2.70 K to 410 ns at 1.8 K following a T -2-dependence. The data are consistent with the values of τ eph previously reported for single-crystal boron-doped diamond films epitaxially grown on diamond substrate. Such a noticeable slow electron-phonon relaxation in boron-doped diamond, in combination with a high normal-state resistivity, confirms a potential of superconducting diamond for ultrasensitive superconducting bolometers. %K superconducting diamond films %K electron-phonon cooling %R 10.1109/TASC.2016.2638199 %U https://ieeexplore.ieee.org/document/7779132/ %U https://doi.org/10.1109/TASC.2016.2638199 %P 1-4
