1. Antenna Integrated Superconducting Mixers
Abstract : This thesis investigates the prospects of some different superconducting mixers integrated with planar antennas for the millimeter and submillimeter regime. Two kinds of Superconductor/Insulator/Superconductor (SIS) tunnel junctions for use in mixers have been fabricated; Nb/PbBi edge junctions and Nb trilayer junctions. READ MORE

5. Theory of Electron Transport in Superconducting Heterostructures
Abstract : This thesis deals theoretically with electron transport in superconducting heterostructures. Depending on the system I use different theoretical approaches. The thesis contains an introduction followed by four research papers (Papers I-IV). The introduction gives the background of the work in Papers I-IV. READ MORE
