Sammanfattning : .... LÄS MER
2. Direct Write Technology of SIN Tunnel Junctions for Thermometry and Microwave Devices
Sammanfattning : This thesis concerns development of SIN junction technology for thermometry and microwave detectors, as well as technology of a planar phase switch as a part of integratedmicrowave receiver.Cold-Electron Bolometer (CEB) is a sensitive detector of a microwave radiation, in which SIN tunnel junctions are used for temperature measurement of a nanoscale absorber in thesame way as in SIN thermometers.

3. Coulomb Blockade Thermometry and Other Aspects of Tunnel Junction Arrays
Sammanfattning : This report describes experimental results on a few different aspects of two-dimensional tunnel junction arrays: Coulomb blockade thermometry (CBT), Hall effect and Josephson array magnetometry (JAM). CBT is a primary thermometry method which is only a few years old. It is suitable for cryogenic temperatures between 20 mK and 30 K. LÄS MER
4. Time-resolved detection of temporally correlated, single-charge tunnelling
Sammanfattning : 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. LÄS MER
5. Ultrasensitive Cold-Electron Bolometer
Sammanfattning : The Cold-Electron Bolometer (CEB) is an ultrasensitive device designed for the detection of cosmic microwave background radiation. The key to its sensitivity is the electron cooling of the absorber by the superconductor-insulator-normal metal (SIN) tunnel junction. LÄS MER
