  1. 1. (1,3-di-tert-butyltriazenide) Cu(I) as vapor deposition precursor

    Kandidat-uppsats, Linköpings universitet/Kemi

    Författare :Peggy Bagherzadeh; [2023]
    Nyckelord :Vapor deposition; CVD; ALD; triazenide;

    Sammanfattning : In the past few decades, devices such as computers have become smaller, and their performance has improved beyond comparison. Semiconductors and interconnectors are used in almost all devices today and are made of thin films. LÄS MER

  3. 2. Feasibility Study of X-ray Free Electron Lasers in Fourth Generation Storage Rings

    Kandidat-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen; Lunds universitet/MAX IV-laboratoriet

    Författare :Jordis Hansen; [2023]
    Nyckelord :XFEL; Storage Ring; Synchrotron Radiation; Physics and Astronomy;

    Sammanfattning : This thesis studies the feasibility of a cavity based X-ray free electron laser in a fourth generation storage ring. The cavity design allows for modulation of the electron beam over several passes through the undulator. Simulations based on the PETRA IV facility are done to create the photon flux spectrum of a light pulse produced by an undulator. LÄS MER

  4. 3. Improving polarizing neutron optics by introducing 11B4C as interlayers

    Master-uppsats, Linköpings universitet/Tunnfilmsfysik

    Författare :Martin Falk; [2023]
    Nyckelord :Thin film multilayers; Neutron optics; Neutron polarization;

    Sammanfattning : In this report, the effects of adding 11B4C as interlayers into Fe/Si multilayers is studied. Fe/Si multilayers are commonly used for neutron polarization at large research facilities, and improving the polarizing properties would improve their efficiency. LÄS MER

  5. 4. Preparation and Characterization of Tb-Co Magnetic Films

    L2-uppsats, Uppsala universitet/Materialfysik

    Författare :Roméo Beignon; [2022]
    Nyckelord :Thin Film; TbCo; Out-of-Plane Anisotropy; Magnetic Domains;

    Sammanfattning : Thin films of terbium-cobalt alloy have been deposited by magnetron sputtering. They exhibit an out-of-plane magnetic anisotropy that may result in elongated domains. The effect of thicknesses and compositions on the domain structure has been studied systematically. LÄS MER

  7. 5. Frontier materials at the air-liquid interface: Self-assembly of green ionic liquids

    Kandidat-uppsats, KTH/Yt- och korrosionsvetenskap

    Författare :Ulrika Karlson; Morgan Ölander; Fernando Zevallos; [2021]
    Nyckelord :Ionic liquids; Green chemistry; X-ray reflectivity; AIR-liquid interface; Self assembly; Jonvätskor; Grön kemi; Självorganisation;

    Sammanfattning : The interfacial structuring of three non-halogenated ionic liquids was examined at the air-liquid interface for both dry and humid condition by analysis of X-ray reflectometry data using a slab model approach. The aim was to investigate the effect of humidity on the air-liquid interface. LÄS MER
