  2. 1. Noise Properties of the Single Electron Transistor

    Author : Serguei Kafanov; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Low-Frequency noise; Shot Noise; 1 f noise; Single Electron Transistor; charge sensitivity; SET; electrometer; Coulomb blockade; radio-frequency Single Electron Transistor; RF-SET;

    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

  5. 3. Current measurement by real-time counting of single charges

    Author : Jonas Bylander; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; array of tunnel junctions; Coulomb blockade; radio frequency single electron transistor; SET oscillations; time correlated tunnelling; metrology; current standard; SET; charge solitons;

    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.

  6. 4. Time-resolved detection of temporally correlated, single-charge tunnelling

    Author : Jonas Bylander; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Josephson junctions; time-correlated tunnelling; radio-frequency single-electron transistor; current standard; charge solitons; SET oscillations; Coulomb blockade; metrology; SET; tunnel junction array;

    Abstract : We report real-time detection of the single charges that constitute a small electrical current, as they flow through a nano-electronic device. This represents a direct demonstration of charge discreteness in an electrical current. READ MORE

  7. 5. Fabrication and Characterization of Aluminum Single Electron Transistors for Scanning Probes

    Author : Henrik Brenning; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; radio frequency single electron transistor; scanning probe; charging energy; nano fabrication; noise; scanning SET; SET; cantilever; AFM; RC-product; micro mechanics;

    Abstract : The main objective of the work presented in this thesis was to fabricatescanning single electron transistor probes that operate at pumped liquid heliumtemperatures. This required single electron transistors (SETs) with low resistance (R_) and relatively high charging energy (E_C), and the technology tointegrate SETs onto probes. READ MORE
