| Summary: | 碩士 === 國立交通大學 === 電子物理系所 === 103 === We investigate the influence of electromagnetic noise on the measurement of mesoscopic samples. Using a Nickel film, we show that the electron temperature of the sample can remain above that of the cryostat. This may be due to high frequency noise reaching the sample. We demonstrate the influence of this noise on the properties of a superconducting SET, and use different filters to improve the measurement. We find that metal film resistors give good filtering, allowing us to characterize the SET device. We find that our SET device is suitable for sensitive charge detection experiments.
