  1. 6. Electronic excitation, luminescence and particle emission : Studying ion-induced phenomena in ToF-MEIS

    Författare :Svenja Lohmann; Daniel Primetzhofer; Friedrich Aumayr; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TOF-MEIS; ion beam analysis; deep UV; desorption; electronic sputtering; TiN;

    Sammanfattning : Medium energy ion scattering (MEIS) is an experimental technique for the high-resolution depth profiling of thin films. Commonly, ions with energies between several ten to a few hundred keV are employed as probes, and backscattered particles are detected. LÄS MER

  3. 7. Material migration in tokamaks: Studies of deposition processes and characterisation of dust particles

    Författare :Armin Weckmann; Marek Rubel; Per Petersson; Daniel Primetzhofer; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; tokamak; fusion; plasma; material migration; particle transport; TEXTOR; PWI; plasma-wall interaction; plasma facing components; PFC; PFM; plasma facing materials; ALT limiter; MoF6; tracer experiment; molybdenum hexafluoride; future energy source; fuel retention; deuterium retention;

    Sammanfattning : Thermonuclear fusion may become an attractive future power source. The most promising of all fusion machine concepts is the tokamak. Despite decades of active research, still huge tasks remain before a fusion power plant can go online. One of these important tasks deals with the interaction between the fusion plasma and the reactor wall. LÄS MER

  4. 8. Synthesis and In Situ ToF-LEIS Analysis of Ultrathin Silicides and Ti-based Films

    Författare :Philipp Mika Wolf; Daniel Primetzhofer; Zhen Zhang; Eduardo Pitthan; Tuan Thien Tran; Anders Hallén; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ion scattering; in situ characterization; nickel silicide; ultrathin metal silicide; epitaxial silicide; surface analysis; titanium based films; high-resolution depth profiling;

    Sammanfattning : Thin films and coatings play a significant role in today’s society, with applications in electronics, optics, mechanics, and biomedicine. Further advancement in the field of surface coatings requires a good understanding of the unique features of ultrathin films and surfaces, which can only be reached with analysis techniques capable of resolving composition and morphology on a sub-nm scale.
