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

    Författare :Sara Green; Gunnar Niklasson; Claes-Göran Granqvist; Esteban Avendaño; Aline Rougier; Uppsala universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 2. Deposition of Al-doped ZnO films by high power impulse magnetron sputtering

    Författare :Martin Mickan; David Horwat; Ulf Helmersson; Aline Rougier; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Transparent conducting oxides (TCOs) are an important class of materials with many applications such as low emissivity coatings, or transparent electrodes for photovoltaics and flat panel displays. Among the possible TCO materials, Al-doped ZnO (AZO) is studied due to its relatively low cost and abundance of the raw materials. LÄS MER

  4. 3. Dynamic and quasi-stationary electrochromic response of amorphous tungsten oxide thin films : In situ combined electrochemical and optical measurements during lithium intercalation

    Författare :Edgar Alonso Rojas González; Gunnar Niklasson; Aline Rougier; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Electrochromism; Optical absorption; Amorphous materials; Tungsten oxide; Electrochemical impedance spectroscopy; Color impedance spectroscopy; Intercalation; Engineering Science with specialization in Solid State Physics; Teknisk fysik med inriktning mot fasta tillståndets fysik;

    Sammanfattning : Electrochromic (EC) materials can adjust their optical properties, reversibly, by means of an external electrical stimulus. They have relevant technological applications; for example, energy-efficient smart windows, which can adapt dynamically—according to the given environmental conditions—to control the heat and visible light fluxes between the interior and exterior of a building.
