  4. 2. Focused Ion Beam Preparation and Transmission Electron Microscopy of Materials for Energy Applications

    Author : Filip Lenrick; NanoLund; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; transmission electron microscopy; focused ion beam; solid oxide materials; fuel cell; semiconductor materials; nanowire; LED; solar cell;

    Abstract : Throughout this thesis, samples of various materials with applications in energy converting devices have been prepared by focused ion beam machining and investigated by transmission electron microscopy. Energy converting devices can be solar cells or light emitting diodes, which turn light into electricity or vice versa. READ MORE

  5. 3. Direct writing with an MeV proton beam: Development and Applications

    Author : Vaida Auzelyte; Kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; direct writing; beam control; Physics; Fysik; Teknik; Technological sciences; proton beam; lithography; Fysicumarkivet A:2006:Auželytė;

    Abstract : This thesis presents work aimed at the development and application of a new lithography system for direct material patterning with the MeV proton beam at the Lund Nuclear Microprobe (NMP) facility. MeV proton beams are advantageous for use as a patterning tool due to their deep and well defined penetration through matter and their highly local energy deposition. READ MORE

  6. 4. Assembling of a low energy ion beam analysis facility and use of Nuclear Microprobe techniques in geological studies

    Author : Rogério José Utui; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; zonation; low energy IBA; Ion beam analysis; Nuclear Microprobe; Micro PIXE; Ionoluminescence IL ; geological applications; Fysicumarkivet A:1996:Utui; Kärnfysik; Nuclear physics; geothermometry.;

    Abstract : In about four decades, ion beam analysis (IBA) techniques have evolved to become well established analytical techniques for routine analysis in archaeological, bio-medical, geological and environmental sciences. They basically make use of the different interactions of a high energy ion beam (of few MeV/amu) with the specimen matter so they pressupose the use of a particle accelerator. READ MORE

  7. 5. Development of Techniques for 3D Imaging with Focused Ion Beams - Hydrogen Depth Profiling and Microtomography with Applications in Geology

    Author : Marie Wegdén; Kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Hydrogen analysis; Depth profiling; Ion beam analysis; Nuclear microprobe; Physics; Nuclear physics; Fysik; Fysicumarkivet A:2007:Wegdén; Kärnfysik; Tomography; 3D Imaging;

    Abstract : In nuclear microprobe experiments, high resolution maps of the measured parameter, e.g. element- or mass distribution, in a sample can be produced with a variety of ion beam analytical techniques. The principle underlying all the techniques is that ions at MeV energies are used as projectiles to cause interactions with the target material. READ MORE
