    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Coplanar; Waveguide; Resonator; Superconductive; Fabrication; Characterization; Superconductivity; Supraledning;

    Abstract : The objective of this thesis is to evaluate a generic process for fabrication and characterization of the Superconductive coplanar waveguide (CPW) resonators. Superconductive CPW resonators with various lengths and shapes are designed to investigate their electrical and magnetic properties as well as resonance properties and sensitivities. READ MORE

  5. 3. Josephson Junctions: Oscillators and Broadband Spectrometers at Frequencies up to 1 THz

    Author : Jonas Edstam; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis is devoted to some selected applications of the Josephson junction oscillator. The initial work was performed using low-Tc Nb/PbBi tunnel junctions, while the later parts were done using the recently developed high-Tc YBa2Cu3O7 (YBCO) Josephson junctions. READ MORE

  6. 4. Thermodynamic characterization of superconducting and magnetic materials using nanocalorimetry

    Author : Donato Campanini; Andreas Rydh; Christoph Meingast; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nanocalorimetry; Superconductivity; Magnetism; MEMS; Specific heat; Thermodynamics; Physics; fysik;

    Abstract : Measurement of specific heat is a powerful technique for the investigation of novel materials. Superconducting and magnetic systems, in particular, can be thoroughly characterized by studying their electronic contribution to the specific heat. READ MORE

  7. 5. Dynamics and Applications of Long Josephson Junctions

    Author : Yongming Zhang; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The first object of this work is to theoretically study the effects of tunnel junction parameters on flux-flow Josephson oscillators (FFOs) by numerical simulation and to experimentally study the rf properties of FFOs by integrating them together with an SIS (superconductor-insulator-superconductor) mixer/detector on a chip. By using a CAD modeled integrated sub-mm wave receiver, the composite linewidth of two FFOs was measured to be less than 2. READ MORE
