摘要:
The performance of diffused planar germanium thermometers is found to be reliable at temperaturesT>90 mK. At lower temperatures performance can be limited by overheating caused by measuring and spurious currents. The heating is associated with a thermal impedanceZ∝T−4which is larger than that found in typical bulk germanium thermometers. Surprisingly,Zis found to be essentially independent of the size of the planar resistor.
