  2. 21. Cathodic arc deposition process

    Author : Muhammad Bilal Syed; Magnus Odén; Jianqiang Zhu; Lars Hultman; Zdeněk Hubička; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This thesis aims to expand the knowledge of fundamental mechanisms that govern the cathodic arc process. The first part of this thesis explores and explains the correlations between a rather unexplored process parameter (i.e. cathode microstructure) and the microstructure of the coatings. READ MORE

  4. 22. 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

  5. 23. Dynamics of Molecular Adsorption on Metal Surfaces

    Author : Christer Engdahl; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : In this Thesis different aspects of dissociative chemisorption and of scattering and trapping in a physisorption potential are investigated, mainly by means of classical trajectory calculations. In papers I-III the sticking coefficients of hydrogen on copper and nickel are calculated using a multidimensional effective-medium potential which takes the molecular orientation as well as the surface structure into account.

  6. 24. From Oxygen to Oxide: First-Principles Study of Some Key Aspects

    Author : Behrooz Razaznejad; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; potential-enrgy surface; one-dimensional electron gas; adsorption; density functional theory; oxidation; Peierls instability; molecule-surface interaction; plane waves;

    Abstract : Having important technological applications and interesting fundamental science aspects, oxidation of aluminum has received impressive attention. Technologically, the main reason for the great interest is the fact that the oxide film which forms on aluminum protects the surface against further oxidation and corrosion. READ MORE

  7. 25. Magnesium Diboride (MgB2) and Ca-doped YBa2Cu3O7-? : Thin Films and Devices. Fabrication and Characterization

    Author : Anayesu Malisa; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ca-doped YBa2Cu3O7-?; MgB2; bicrystal; superconductor; nanobridge; thin film; Josephson effect; Josephson junction;

    Abstract : Magnesium diboride (MgB2) is a superconductor with an exceptionally high transition temperature, Tc, of 39 K. This work describes deposition of high quality and superconducting films of MgB2 for electronic applications. Experiments on Ca-doped YBa2Cu3O7-? films and fabrication of bicrystal Josephson junctions are also described. READ MORE
