The authors are developing a 20mK temperature sensor made of neutron transmutation doped (NTD) germanium for use as a phonon detector in a dark matter search. They find that NTD germanium thermistors around 20 mK have resistances which are a strong function of temperature, and have sufficient sensitivity to eventually reach a base line rms energy fluctuation of 6eV at 25 mK. Further work is needed to understand the extreme sensitivity of the thermistors to bias power.
