6. Nanoscale YBa2Cu3O7-δ devices -Searching for a subdominant order parameter using a single electron transistor
Sammanfattning : The microscopic origin of High critical Temperature Superconductivity (HTS) is still an open issue in condensed matter physics. It is believed that by exlporing the quasiparticle energy spectrum one can learn about the mechanism promoting the superconducting state. LÄS MER
7. Correlations mediated by Cooper pairs in single-electron devices
Sammanfattning : .... LÄS MER
8. Metal and Semiconductor Nanocrystals for Quantum Devices
Sammanfattning : Aerosol technology was used to develop new methods for fabrication of size-selected, nanometer-sized particles of metals and semiconductors. Such particles were used to realize different types of quantum devices and nanometer-sized structures. LÄS MER
9. Fast dynamics and measurements of single-charge devices
Sammanfattning : In this thesis we present measurements on several different devices, including the single-Cooper-pair box (SCB), the single-electron box, tunable superconducting resonators and so called transmon qubits.By exploiting the quantum capacitance of the SCB, its state was measured by embedding the box in a radio-frequency resonator.

10. Quantum Devices from the Assembly of Zero- and One-Dimensional Building Blocks
Sammanfattning : This thesis describes novel methods for the fabrication of nanometer-scale electronic devices, such as single-electron transistors and resonant tunneling diodes, from wire- and dot-shaped building blocks. The first part of the thesis describes the manipulation of metal nanoparticles and carbon nanotubes using an atomic force microscope. LÄS MER
