Abstract

A thermometer that relies on different types of noise to measure temperature over four orders of magnitude was developed. The crossover between the shot noise and Jhonson noise regimes was detected, which depended on temperature. Shot noise thermometer was demonstrated over a temperature range that spanned from room temperature down to 0.01 K. Measurements agree with those from standard secondary thermometers, and are accurate to within 0.1% at a temperature of 1 K.
