  1. 1. The role of interfaces in oxide thin films

    Författare :Tomas Liljenfors; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; thin film; LSMO; EELS; grain boundary; BSTO; interfaces; LCMO; manganites; BTO; bicrystal; TEM; HRTEM; microstructure;

    Sammanfattning : The role of interfaces in oxide thin films has been investigated from a microstructural point of view. Thin films of manganites and titanates have been investigated by transmission electron microscopy (TEM). LÄS MER

  3. 2. Gyrokinetic simulations of turbulent particle and heat transport in tokamaks

    Författare :Daniel Tegnered; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; tokamak; plasma physics; turbulence; transport; gyrokinetics; TEM; ITG; impurities; fusion; Joint European Torus;

    Sammanfattning : Fusion power is one of few viable sustainable means of energy production. The tokamak is arguable the most mature technology to magnetically confine fusion plasmas. In these devices, heat and particle transport is dominated by small-scale turbulent fluctuations. LÄS MER

  4. 3. High-resolution characterization of TiN diffusion barrier layers

    Författare :Marlene Mühlbacher; Lars Hultman; Christian Mitterer; Lars Johnson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diffusion; TiN; Microstructure; Transmission electron microscopy; TEM; Atom probe tomography; APT;

    Sammanfattning : Titanium nitride (TiN) films are widely applied as diffusion barrier layers in microelectronic devices. The continued miniaturization of such devices not only poses new challenges to material systems design, but also puts high demands on characterization techniques. LÄS MER

  5. 4. Study on the Mechanisms for Corrosion and Hydriding of Zircaloy

    Författare :Magnus Oskarsson; KTH; []
    Nyckelord :Zircaloy; Zirconium alloys; Oxidation; Oxide layer; Pre-Transition; Hydriding; Pre-Hydrided; Hydrides; Lithium Hydroxide LiOH ; Lithiated water; Dissolution; Cross sectional TEM;

    Sammanfattning : This thesis is focused on the mechanisms for corrosion andhydriding of Zircaloy. Special attention is paid tomicrostructural characterisation by cross sectionaltransmission electron microscopy of the oxide layer formed. LÄS MER

  7. 5. Development of Transmission Electron Microscopy Techniques for the Study of Thin Films

    Författare :John P. McCaffrey; Bender Hugo; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Transmission electron microscopy (TEM) is an invaluable tool for the study of the physics and materials properties of thin films. This thesis addresses innovations and novel applications of TEM to materials physics, and consists of three parts: the examination and development of innovative TEM sample preparation techniques, conventional selected area electron diffraction with new techniques for data extraction, and an extended TEM investigation of quantum dots.
