  1. 1. Electronic Structure and Film Morphology Studies of PTCDI on Metal/Semiconductor Surfaces

    Författare :Christian Emanuelsson; Hanmin Zhang; Lars Johansson; Ellen Moons; Mats Ahmadi Götelid; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PTCDI; STM; LEED; XPS; UPS; NEXAFS; Organic Films; Semicondcutor Surfaces; Electronic Structure; Molecular Interactions; Film Morphology; Physics; Fysik;

    Sammanfattning : Organic semiconductors have received increasing attention over the last decades as potential alternatives for inorganic semiconductors. The properties of these films are highly dependent on their structural order. LÄS MER

  3. 2. Bonding and Desorption Mechanismsof CO on Metal Surfaces

    Författare :Jörgen Gladh; Henrik Öström; Mats Götelid; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bonding; Desorption; CO; Metal; kemisk fysik; Chemical Physics; fysik; Physics;

    Sammanfattning : I have investigated two different systems CO/Fe(100) and CO/Ru(0001), toobtain new information on the binding and desorption processes. The twodifferent systems have served as a model system, one for a static examination,CO on iron, and for the dynamic case, CO on ruthenium. LÄS MER

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tar reforming; biomass gasification; Ni-based catalyst; potassium; sulfur; pyrolysis gas; bio-crude conditioning; gas conditioning; Fe-based catalyst; tjärreformering; biomassaförgasning; Ni-baserad katalysator; kalium; svavel; pyrolysgas; konditionering bio-råolja; gaskonditionering; Fe-baserad katalysator; Chemical Engineering; Kemiteknik;

    Sammanfattning : Reliable energy supply is a major concern and crucial for development of the global society. To address the dependency on fossil fuel and the negative effects of this reliance on climate, there is a need for a transition to cleaner sources. An attractive solution for replacing fossil-based products is renewable substitutes produced from biomass. LÄS MER

  5. 4. Synchrotron radiation study of free and adsorbed organic molecules

    Författare :Teng Zhang; Carla Puglia; Nils Mårtensson; Svante Svensson; Mats Götelid; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Synchrotron radiation; Phthalocyanine; Cobalt phthalocyanine; Biphenylene; Functional materials; CoPc; Photoemission spectroscopy; Absorption spectroscopy; PES; XAS; Electronic structure; Gas phase; film; Organic molecule;

    Sammanfattning : In this licentiate thesis, organic molecules, namely Cobalt Phthalocyanine (CoPc) and Biphenylene, have been studied by means of synchrotron radiation-based spectroscopic methods (Photoemission Spectroscopy (PES) and X-ray Absorption Spectroscopy (XAS) in combination with Density Functional Theory (DFT) calculations.Paper I is a combined experimental and theoretical investigation of electronic structure of CoPc.
