  2. 1. Spectrally Selective Solar Absorbing Coatings Prepared by dc Magnetron Sputtering

    Author : Shuxi Zhao; Ewa Wäckelgård; Carl-Gustaf Ribbing; Volker Wittwer; Uppsala universitet; []
    Keywords : Materials science; spectrally selective surface; solar energy; magnetron sputtering; thin film; Materialvetenskap;

    Abstract : Spectrally selective solar absorber using composite Ni-NiO as coating materials was studied. Samples were prepared by dc magnetron sputtering unit named Rulle, which is a miniature copy of an industrial roll-coater unit. READ MORE

  4. 2. Electrochromic Nickel – Tungsten Oxides : Optical, Electrochemical and Structural Characterization of Sputter-deposited Thin Films in the Whole Composition Range

    Author : Sara Green; Gunnar Niklasson; Claes-Göran Granqvist; Esteban Avendaño; Aline Rougier; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrochromism; Nickel oxide; Tungsten oxide; Lithium intercalation; Sputtering; Thin films; Nanostructures; Optical properties; Solid State Physics; Fasta tillståndets fysik;

    Abstract : This thesis investigates the electrochromic NixW1-x oxide thin film system, where 0 < x < 1. The thin films were deposited by reactive DC magnetron co-sputtering from one Ni and one W metal target. In addition, Ni oxide was deposited with water vapor added to the sputtering gas. READ MORE

  5. 3. Self Lubrication on the Atomic Scale : Design, Synthesis and Evaluation of Coatings

    Author : Mattias Lindquist; Sture Hogmark; Urban Wiklund; Ian Hutchings; Uppsala universitet; []
    Keywords : Materials science; Tribology; low friction; PVD; sputtering; nanocomposite; Materialvetenskap;

    Abstract : In this thesis a new design concept of tribologically active coatings aimed for low friction applications, have been explored. Materials modeled by ab initio DFT calculations were realized through deposition of carbide and nanocomposite coatings by DC-magnetron sputtering. READ MORE

  6. 4. Fundamentals of High Power Impulse Magnetron Sputtering

    Author : Johan Böhlmark; Ulf Helmersson; André Anders; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Plasma; Pulsed plasma; High Power Pulsed Magnetron Sputtering; Plasma Characterization; Physics; Fysik;

    Abstract : In plasma assisted thin film growth, control over the energy and direction of the incoming species is desired. If the growth species are ionized this can be achieved by the use of a substrate bias or a magnetic field. Ions may be accelerated by an applied potential, whereas neutral particles may not.

  7. 5. Toward Energy-efficient Physical Vapor Deposition : Routes for Replacing Substrate Heating during Magnetron Sputtering by Employing Metal Ion Irradiation

    Author : Xiao Li; Grzegorz Greczynski; Ivan Petrov; Lars Hultman; Jyh-Wei Lee; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; PVD; Magnetron sputtering; Thin films; HiPIMS; TiAlN; Energy efficiency;

    Abstract : In this Thesis, magnetron sputtering is perfected as an environmental-friendly deposition technique. I performed systematic studies of a novel approach - hybrid high-power impulse and dc magnetron co-sputtering (HiPIMS/DCMS) with metal-ion-synchronized substrate bias pulses. READ MORE
