  1. 21. Properties of small Bi2Sr2CaCu2O8 intrinsic Josephson junctions: confinement, flux-flow and resonant phenomena

    Författare :Sven-Olof Katterwe; Vladimir M. Krasnov; Alexey Ustinov; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; high-temperature superconductivity; intrinsic Josephson junctions; tunneling; fluxons; flux-flow oscillator; THz-emission; cavity resonances; polaritons; micro nano-fabrication; fysik; Physics;

    Sammanfattning : In this thesis, intrinsic Josephson junctions, naturally formed in the strongly anisotropic high-temperature superconductor Bi2Sr2CaCu2O8 (Bi-2212), are studied experimentally. For this purpose, small mesa structures are fabricated on the surface of single crystals using micro- and nano-fabrication tools, focused ion beam is used to reduce the area of the mesa-structures down to ≈ 1 × 1 μm2.

  7. 25. Biology of Borrelia garinii Spirochetes

    Författare :Pär Comstedt; Sven Bergström; Wolfram R. Zückert; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Borrelia garinii; Lyme borreliosis; birds; migration; reservoir host; complement; Ixodes ricinus; Europe; Asia; infection cycle; Molecular biology; Molekylärbiologi;

    Sammanfattning : Lyme borreliosis is a tick-transmitted infectious disease. The causative agents are spiral-shaped bacteria and the most common sign of infection is a skin rash at the site of the tick bite. LÄS MER
