Radio Frequency-Single Electron Transistor: A Fast and Sensitive Electrometer Analogous to the Radio Frequency-Superconducting Quantum Interference Device
We describe a new mode of operation of the single electron transistor (SET). The so-called RF-SET (radio frequency-SET) is a dual of the RF-SQUID (radio frequency-superconducting quantum interference device). It has been operated at frequencies above 100 MHz with a very high charge sensitivity (1.2 3 10e/ÏHz). The large bandwidth, combined with a high sensitivity, will enable studies of the dyn...
متن کاملThe radio-frequency single-electron transistor (RF-SET): A fast and ultrasensitive electrometer
A new type of electrometer is described that uses a single-electron transistor (SET) and that allows large operating speeds and extremely high charge sensitivity. The SET readout was accomplished by measuring the damping of a 1.7-gigahertz resonant circuit in which the device is embedded, and in some ways is the electrostatic "dual" of the well-known radio-frequency superconducting quantum inte...

متن کاملNumerical 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 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...
