  3. 18. Electronic structure studies and method development for complex materials

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Andreas Östlin; KTH.; [2013]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electronic structure theory; transition metals; method development;

    Sammanfattning : Over the years electronic structure theory has proven to be a powerful method with which one can probe the behaviour of materials, making it possible to predict properties that are difficult to measure experimentally. The numerical tools needed for these methods are always in need of development, since the desire to calculate more complex materials pushes this field forward. LÄS MER

  4. 19. Investigations of Transition Metal Systems : Angle-Resolved Photoelectron Spectroscopy at Low and High Energy

    Detta är en avhandling från Stockholm : KTH

    Författare :Thomas Claesson; KTH.; [2007]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; angle-resolved photoelectron spectroscopy; electronic structure; oxides; high-temperature superconductors; TECHNOLOGY Engineering physics Material physics with surface physics; TEKNIKVETENSKAP Teknisk fysik Materialfysik med ytfysik;

    Sammanfattning : The work presented in this thesis aims at achieving an increased understanding of the electronic structure of materials whose properties are to a large extent governed by transition metals. All studies are based on data from angle-resolved photoelectron spectroscopy (ARPES) employed on the valence band of the studied systems. LÄS MER

  5. 20. Hydrogen in nano-sized metals Diffusion and hysteresis effects

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Wen Huang; Uppsala universitet.; [2017]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hydrogen; diffusion; hysteresis; optical technique; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Sammanfattning : Metal hydrides can be used as hydrogen storage materials for fuel cells and batteries, and as sensors for detecting hydrogen gas. The use of metal hydrides for hydrogen storage can be hindered by poor kinetics and low capacity. Moreover, poor sensitivity, long recovery and response time, limit the applications of metal hydrides as hydrogen sensors. LÄS MER
