Abstract

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 × 10−5 e/√Hz. The large bandwidth, combined with a high sensitivity, will enable studies of the dynamics of mesoscopic systems on very short time scales.

  10. The voltage reflection coefficient is given by (Z − Z 0)/(Z + Z 0). When Z = RT ≫ Z 0, the total reflected power is proportional to 1 − 4 Z 0/RT. We assume that the impedance of the transistor, R T, is very large at maximum blockade.
