ABSTRACT
We have measured the third derivative of the current-voltage characteristics, d[sup 3]I/dV[sup 3], in a two-dimensional array of small tunnel junctions using a lock-in amplifier. We show that this derivative is zero at a voltage which scales linearly with the temperature and depends only on the temperature and natural constants, thus providing a primary thermometer. We demonstrate a measurement method which extracts the zero crossing voltage directly using a feedback circuit. This method requires only one voltage measurement, which makes it substantially faster than the original Coulomb blockade thermometry method. © 2001 American Institute of Physics.

    The authors report measurements of the shot noise thermometer (SNT), a primary thermometer based on the electronic noise from a tunnel junction, in the range from 10 to 200 mK. They demonstrate operation of the SNT down to 10 mK with 10% accuracy at the lowest measured temperature. At 10 mK,...
