1. Noise Properties of the Single Electron Transistor
Abstract : 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. READ MORE

2. The Radio Frequency Single-Electron Transistor: Noise Properties and its Potential for Detecting Electrons on Helium
Abstract : In this thesis the noise in the single electron transistor (SET) has been investigated.The charge sensitivity for the radio frequency single electron transistor(RF-SET) was measured. The demonstrated result is better than the previouslybest reported value both at 40 mK, and at 4.2 K. READ MORE

3. The Radio Frequency Single-Electron Transistor and the Horizon Picture for Tunneling
Abstract : 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. READ MORE

4. Quantum Coherence in the Single Cooper Pair Box
Abstract : 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. READ MORE

5. Current measurement by real-time counting of single charges
Abstract : The first real-time observation of time correlated single-electron tunnelling is reported in this thesis. This is a direct detection of charge discreteness in an electrical current.When a current, I, flows through a chain of metallic islands, connected by small tunnel junctions, a lattice of charges is formed due to the Coulomb repulsion.
