1. Noise Properties of the Single Electron Transistor
Sammanfattning : The Single Electron Transistor (SET) is a sensitive electrometer with a charge sensitivityultimately limited by noise. In this thesis we present measurements of noiseproperties and charge sensitivity of the radio-frequency Single Electron Transistor. LÄS MER
2. Studies of acoustic waves, noise and charge pumping using single-electron devices
Sammanfattning : This thesis covers a range of experiments on single-electron devices, electrical circuits that utilize the discreetness of the electron charge. The Single-Electron Transistor (SET) is of special importance among these, being the most sensitive electrometer demonstrated, and sufficiently mature to serve as a building block in sensors and detectors for physical phenomena that can be transformed into charge signals.

3. The Radio Frequency Single-Electron Transistor and the Horizon Picture for Tunneling
Sammanfattning : The main part of this thesis concerns the development of a new type of single electron transistor (SET) called the radio frequency single electron transistor (RF-SET). The RF-SET is the most sensitive electrometer demonstrated. LÄS MER
4. Quantum Coherence in the Single Cooper Pair Box
Sammanfattning : This thesis presents measurements of quantum coherence in a single Cooper pair box, where quantum oscillations of charge between a reservoir and a small superconducting island have been observed. The single Cooper pair box (SCB) consists of a small metallic island which is connected to a reservoir via a tunnel junction. LÄS MER
5. The Single Cooper Pair Box - a Quantum-Mechanical Electronic Circuit
Sammanfattning : In this thesis the single Cooper pair box (SCB) is investigated with a radio frequency single electron transistor (RF-SET). The RF-SET is used as an electrometer to detect the charge of the SCB. The SCB can be regarded as a quantum two-level system and could therefore be a possible qubit. LÄS MER
