Neutron Transmutation Doped Germanium have a very uniform distribution of dopants and can work as thermistor at ultra-low (10 mK) temperature when using Bolometric detection technique. NTD-Ge have played a critical role in many rare events searching experiments. We produced a batch of NTD-Ge samples by thermal neutron irradiation and fabricated several NTD-Ge thermistors. We did some fundamental studies such as annealing of radiation defects produced by fast reactor neutrons and carrier concentration using variable temperature Hall-effect to determine the properties of NTD-Ge. The resistance-temperature relationship measurements are to be carried out to characterize the NTD-Ge thermistor in the near future.
