Query: Non-galvanic primary thermometry of a two-dimensional electron gas   We report the experimental realization of a non-galvanic, primary thermometer
capable of measuring the electron temperature of a two-dimensional electron gas
with negligible thermal load. Such a thermometer consists of a quantum dot
whose temperature-dependent, single-electron transitions are detected by means
of a quantum-point-contact electrometer. Its operating principle is
demonstrated for a wide range of electron temperatures from 40 to 800 mK. This
noninvasive thermometry can find application in experiments addressing the
thermal properties of micrometer-scale mesoscopic electron systems, where
heating or cooling electrons requires relatively low thermal budgets.
