  2. 11. HiPIMS-based Novel Deposition Processes for Thin Films

    Author : Asim Aijaz; Ulf Helmersson; Kostas Sarakinos; Linköpings universitet; []
    Keywords : ;

    Abstract : In this research, high power impulse magnetron sputtering (HiPIMS) based new deposition processes are introduced to address; the issue of low degree of ionization of C in magnetron sputtering discharges, and the difficulty encountered in thin film deposition on complex-shaped surfaces. The issue of low degree of C ionization is addressed by introducing a new strategy which is based on promoting the electron impact ionization ofC by increasing the electron temperature in the plasma discharge using Ne, instead of conventionally used Ar.

  4. 12. Synthesis of Carbon-based and Metal-Oxide Thin Films using High Power Impulse Magnetron Sputtering

    Author : Asim Aijaz; Ulf Helmersson; Kostas Sarakinos; Günter Bräuer; Linköpings universitet; []
    Keywords : ;

    Abstract : The work presented in this thesis deals with synthesis of carbon-based as well as metal-oxide thin films using highly ionized plasmas. The principal deposition method employed was high power impulse magnetron sputtering (HiPIMS). READ MORE

  5. 13. Deposition of Al-doped ZnO films by high power impulse magnetron sputtering

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

    Abstract : 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. READ MORE

  6. 14. Controlled growth of metastable Ta3N5 semiconducting films

    Author : Jui-Che Chang; Ching-Lien Hsiao; Jens Birch; Grzegorz Greczynski; Martin Rudolph; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The semiconductor tritantalum pentanitride (Ta3N5) is a promising material for green energy applications, specifically in the photoelectrolysis of water to produce oxygen and hydrogen. With a bandgap of approximately 2 eV, Ta3N5 is well-suited for efficient solar light absorption across a broad spectrum, and its band positions align favorably with the redox potential of water.
