Numerical analysis of radio-frequency single-electron transistor operation
We have analyzed numerically the response and noise-limited charge sensitivity of a radio-frequency singleelectron transistor ~RF-SET! in a nonsuperconducting state using the orthodox theory. In particular, we have studied the performance dependence on the quality factor Q of the tank circuit for Q both below and above the value corresponding to the impedance matching between the coaxial cable ...
متن کاملOperation of single-walled carbon nanotube as a radio-frequency single-electron transistor
We demonstrate the operation of a radio-frequency single-electron transistor (RF-SET) using single-wall carbon nanotubes (SWNTs). The device is embedded in a resonant tank circuit and operates in reflection mode at temperatures as high as 5 K. Both frequency domain and time domain results are presented. With a gate modulation frequency of 1 MHz, a charge sensitivity of ∼4.78 × 10−4e/Hz−1/2 is o...

متن کاملCharacterization of a Differential Radio-Frequency Single- Electron Transistor
We have fabricated and characterized a new type of electrometer that couples two parallel single-electron transistors (SETs) to a radio-frequency tank circuit for use as a differential RF-SET. We demonstrate operation of this device in summing, differential, and single-SET operation modes, and use it to measure a Coulomb staircase from a differential single Cooper-pair box. In differential mode...
متن کاملSingle-shot readout with the radio-frequency single-electron transistor in the presence of charge noise
The radio-frequency single-electron transistor srf-SETd possesses key requirements necessary for reading out a solid state quantum computer. This work explores the use of the rf-SET as a single-shot readout device in the presence of 1 / f and telegraph charge noise. For a typical spectrum of 1/ f noise we find that high fidelity, single-shot measurements are possible for signals Dq .0.01e. For ...
