  1. 1. Characterization of Bi-incorporated InSb(111)A/B Surfaces : An STM and XPS Study

    Master-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Författare :Shengpeng Huang; [2023]
    Nyckelord :indium antimonide; surface reconstructions; bismuth deposition; scanning tunneling microscopy; X-ray photoelectron spectroscopy.; Physics and Astronomy;

    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.

  4. 3. Erosion Behaviour of Thermal Barrier Coatings

    Master-uppsats, Linköpings universitet/Konstruktionsmaterial

    Författare :Caroline Wännman; [2021]
    Nyckelord :erosion; TBC; APS; EB-PVD; PS-PVD; failure mechanisms;

    Sammanfattning : Thermal barrier coatings (TBCs) are advanced material systems used in the hot sections of gas turbines. The TBCs are designed to provide insulation against hot gases by a ceramic top coat and to provide oxidation and corrosion resistance by a metallic bond coat. LÄS MER

  5. 4. Polymer Assisted Transfer of Graphene onto Semiconductor Substrates

    Kandidat-uppsats, Lunds universitet/Förbränningsfysik; Lunds universitet/Synkrotronljusfysik

    Författare :Jonathan Frisby; [2020]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Since first being isolated in 2004, Graphene has been researched heavily because of its unique properties. Recently, interest has grown in graphene/semiconductor heterostructures. In this work, the transfer of graphene through the use of cellulose acetate butyrate (CAB) polymer is studied. LÄS MER

  7. 5. An STM-based study of Bi deposition on InAs(110)

    Kandidat-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Författare :Tobias Alpskog; [2020]
    Nyckelord :Bismuth; Deposition; STM; Physics and Astronomy;

    Sammanfattning : III-V semiconductor compounds containing Bi, such as InBi, have recently attracted much attention due to predictions of band inversion and topological insulators. The predictions showed that films of InBi could be applicable in quantum computers and at room temperature. LÄS MER
