Measurement of cryoelectronics heating using a local quantum dot thermometer in silicon

Fast Thermodynamic Study on a Silicon Nanotransistor at Cryogenic Temperatures

“…While traditional current-based thermometry methods offer reliable cryogenic temperature probing, − they have limited bandwidth due to small tunnelling currents. − In contrast, RF reflectometry, with its high bandwidth capabilities exceeding 1 MHz and compatibility with microwave drive , and light illumination, has emerged as a standard electrical-readout technique for semiconductor quantum electronic devices. − Due to these prospects, RF-reflectometry-based thermometry has been demonstrated across various device types, − and a proof-of-concept thermodynamic study was carried out with observations yet to be fully understood . However, improvements in temperature sensitivity are still needed by addressing measurement noise …”
