Abstract

We have studied particle detectors consisting of neutron transmutation doped (NTD) Ge phonon sensors attached with a eutectic bonding process to large mass germanium crystals. These thermistors remain one of the most performant temperature sensors at temperatures as low as 20 mK. We summarize the experimental evidence for the significant role of non-equilibrium phonons in their observed behavior. However, the difficulties of forming a high transparency interface and the lack of inelastic channels appear to limit their effectiveness as non-equilibrium phonon sensors.
