    • Reliable Packaging and Development of Photodiode Module for Operation at 4 K 

      Bardalen, Eivind (Doctoral dissertations at the University of South-Eastern Norway;5, Doctoral thesis, 2018)
      AC voltage standards based on pulse-driven Josephson junction arrays, operated at 4 K, enable quantum-accurate generation of arbitrary voltage waveforms. These devices are operated by biasing the arrays with high-frequency ...
    • Simulation and microfabrication of MEMS vacuum electronic devices for terahertz technology 

      Billa, Laxma Reddy (Doctoral dissertations at the University of South-Eastern Norway;49, Doctoral thesis, 2019)
      Numerous applications explore the scarcely used terahertz (THz) band in the electromagnetic spectrum. However, widespread utilization of the THz band is technically challenging, due to the lack of power sources. The power ...
    • Smartphone-based urinary biomarker detection: an application-oriented device and algorithm 

      Karlsen, Haakon (Doctoral dissertations at the University College of Southeast Norway;30, Doctoral thesis, 2018)
      Persons of advanced age have a higher risk of contracting urinary tract infection than the general population. Functional impairments, cognitive impairments, urine incontinence and advanced age encumbers the management of ...
    • Solid liquid interdiffusion wafer-level bonding for MEMS packaging
