    Sammanfattning : In recent years, III-V semiconductor materials have received increasing attention due to their admirable electronic properties like direct tunable bandgaps and high charge carrier mobility. Indium Antimonide (InSb) possesses the largest electron mobility among III-V materials and is promising for infrared detectors, high-speed field effect transistors, and spintronics. LÄS MER

  3. 2. Influence of Superconducting Order Parameter on Quasi-Particle Interference

    Master-uppsats, Uppsala universitet/Materialfysik

    Författare :Siri Alva Berge; [2022]
    Nyckelord :;

    Sammanfattning : Superconductors are important to study due to their many applications. Superconductivityarises when electron pairs, so-called Cooper pairs, form in the material.To understand the mechanism behind the formation of the Cooper pairs, the pairingsymmetry, described by the order parameter, must be found.

    Sammanfattning : Topological insulators are electronic materials that behave like an ordinary insulator in their bulk but have robust conducting states on their edge. Besides, in some materials the band structure presents completely flat bands, a special feature leading to strong interactions effects. LÄS MER
