11. MgB2 hot-electron bolometer mixers for sub-mm wave astronomy
Sammanfattning : Spectroscopy and photometry in the terahertz (THz) range of remote space objects allows for a study of their chemical composition, because this range covers rotational lines from simple molecules and electron transition lines from atoms and ions. Due to high spectral resolution, THz heterodyne receivers al- low for studying dynamical properties of space objects manifested in doppler-shifted emission lines. LÄS MER
12. Vortex fluctuations in superconductors
Sammanfattning : The vortex fluctuations have proved to be responsible for the onset of dissipation in thin type-II superconducting Aims. There is also growing evidence that dissipation in high- temperature superconductors exhibits the same kind of two-dimensional (2D) behavior. LÄS MER
13. Refractory High-entropy Alloy and Nitride Thin Films
Sammanfattning : This thesis focuses on understanding the process-structure-property relation-ships for several refractory-metal-based high-entropy alloys and nitrides synthesized by magnetron sputtering. The thesis begins with the growth of TiZrNbTaNx understoichiometric nitrides by controlling substrate temperature and nitrogen flow ratio fN. LÄS MER

15. Experimental Verification of Superconductor Digital Circuits
Sammanfattning : AbstractSuperconducting digital technology based on Rapid Single Flux Quantum (RSFQ) logic offers a 50 times faster clock rate and 100 times less on chip power consumption than today's mainstream semiconductor electronics. This technology is attractive for many applications and in particular for Digital Signal Processing (DSP). LÄS MER
