1. 1. Noise Properties of the Single Electron Transistor

   Författare :Serguei Kafanov; Chalmers tekniska högskola; []
   Nyckelord :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;

   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

3. 2. Studies of acoustic waves, noise and charge pumping using single-electron devices

   Författare :Martin Gustafsson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; single-electron pump; single-electron transistor; surface acoustic wave; single-electron devices; charge pumping; TLF; SINIS turnstile; electrometer; two-level fluctuator; single-photon detector; noise; SAW; SET;

   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.

5. 4. Single-Electron Tunneling Spectroscopy in Magnetic Nanoparticles and Molecular Magnets

   Författare :Lukasz Michalak; Fasta tillståndets fysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; master equation; magnetic nanoparticles; spin accumulation; molecular magnets; TMR; tunneling magnetoresistance; F-SET; ferromagnetic single-electron transistor; single-electron tunneling; nanomagnetism; spintronics; Coulomb blockade;

   Sammanfattning : This thesis deals with single-electron tunneling in transistor-like devices in which the central electrode is either a metal nanoparticle (possibly ferromagnetic) or a molecular magnet. The investigated systems split into two different categories, depending on the size of the central island. LÄS MER

7. 5. Nanofabrication of Single Electron Transistors and Evaluation of Miniature Biosensors

   Författare :Linda G. M. Olofsson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; miniaturization; nanoparticles; impedance; single electron tunneling; biosensors; surface plasmon resonance;

   Sammanfattning : This thesis deals with miniaturization in two different fields: electronics and biosensing. The first part deals with fabrication and measurements of two nanoscale structures - a self-assembled single electron transistor and a (potential) single junction device. LÄS MER
