Abstract

We have measured the electron-phonon interaction in a 2000 Å thick gold film on a quartz substrate in the temperature range of 30 to 200 mK. The magnetization of two small erbium-doped gold sensors was used to determine the temperature of the electrons in the Au and the phonons in the quartz independently. A value of 3.7 × 109 W m-3 K -5 was obtained for the electron-phonon coupling constant. This result provides further evidence that electron-phonon interactions in thin films at low temperatures are dependent upon the properties of the substrate.
