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

    University essay from Linköpings universitet/Kemi

    Author : Peggy Bagherzadeh; [2023]
    Keywords : Vapor deposition; CVD; ALD; triazenide;

    Abstract : 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. READ MORE

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

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen; Lunds universitet/MAX IV-laboratoriet

    Author : Jordis Hansen; [2023]
    Keywords : XFEL; Storage Ring; Synchrotron Radiation; Physics and Astronomy;

    Abstract : 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. READ MORE

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

    University essay from Linköpings universitet/Tunnfilmsfysik

    Author : Martin Falk; [2023]
    Keywords : Thin film multilayers; Neutron optics; Neutron polarization;

    Abstract : 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. READ MORE

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

    University essay from Uppsala universitet/Materialfysik

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

    Abstract : 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. READ MORE

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

    University essay from KTH/Yt- och korrosionsvetenskap

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

    Abstract : 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. READ MORE
