  1. 11. Chemical vapour deposition of boron-carbon thin films from organoboron precursors

    Författare :Maiwulidan (Mewlude) Yimamu (Imam); Henrik Pedersen; Jens Birch; Carina Höglund; Erik Lindahl; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Boron-carbon (BxC) thin films enriched in 10B are potential neutron converting layers for 10Bbased solid-state neutron detectors given the good neutron absorption cross-section of 10B atoms in the thin film. Chemical Vapour Deposition (CVD) of such films faces the challenge that the maximum temperature tolerated by the aluminium substrate is 660 °C and low temperature CVD routes for BxC films are thus needed.

  3. 12. Chemical vapour deposition of sp2-hybridised B-C-N materials from organoborons

    Författare :Laurent Souqui; Anne Henry; Hans Högberg; Henrik Pedersen; John R. Abelson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; boron nitride; epitaxy; CVD; boron carbide; carbonitride; PECVD;

    Sammanfattning : Thin films of sp2-BN are promising materials for graphene and deep-UV optoelectronics. They are typically deposited by thermally activated chemical vapour deposition (CVD) from triethylboron (TEB) and ammonia (NH3) at 1500 °C, albeit in a narrow process window. LÄS MER

  4. 13. Black Death - Blue Skies - White Clouds : Water Vapour Uptake of Particles Produced from Traffic Exhaust and their Effect on Climate

    Författare :Cerina Wittbom; MERGE: ModElling the Regional and Global Earth system; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CCN ACTIVATION; Soot; water vapour; climate; SOA; Traffic emission; Fysicumarkivet A:2017:Wittbom;

    Sammanfattning : Aerosol particles are everywhere in the air around us, regardless of whether you are in a busy city or in the serene Arctic. Airborne particles can be produced naturally or anthropogenically, and their properties changes during the time they spend in the atmosphere. LÄS MER

  5. 14. Electronic Properties of Metal Oxide Films Studied by Core Level Spectroscopy

    Författare :Jan Hinnerk Richter; Anders Sandell; Håkan Rensmo; Anne Borg; Uppsala universitet; []
    Nyckelord :Physics; electron spectroscopy; metal oxide; chemical vapour deposition; ion insertion; metal organic; band alignment; zirconium; titanium; silicon; high k; Fysik;

    Sammanfattning : In this dissertation core level electron spectroscopy has been employed to study various aspects of metal oxide films grown under ultra-high vacuum conditions. Studies on in situ ion insertion of lithium into thin TiO2 systems were performed. LÄS MER

  7. 15. Immobilization and Interaction of Biomolecules at the Solid-Liquid Interface : Applications to Solid-Phase Analytical Techniques

    Författare :Ulf Jönsson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Protein immobilization; silica; Immunoglobulins; Protein A; Fibronectin; chemical-vapour deposition; silane; ellipsometry; radiolabeling; contact-angle measurement; solid-phase analytical techniques;

    Sammanfattning : The development of solid-phase-analytical techniques based on surface-concentration-measuring devices requires a stable and reproducible immobilization of biomolecules on well-characterized solid surfaces. This study reports on the immobilization of Immunoglobulin G, Protein A and Fibronectin on chemically modified silica surfaces. LÄS MER
