摘要：

The electron phase coherence length is used as a thermometer to measure the temperature of a 2DEG. We find that the electron temperature differs from the mixing chamber temperature of the refrigerator by as much as 100 mK at base temperature. We also measure the thermal resistance between the electron gas and the mixing chamber and find a resistance comparable to that predicted by the Wiedemann-Franz law for the electron gas alone. Our results indicate an extraneous power level of about 4 pW in our experimental configuration.
