  2. 21. A Study of Group 13-Nitride Atomic Layer Deposition : Computational Chemistry Modelling of Atomistic Deposition Processes

    Author : Karl Rönnby; Lars Ojamäe; Henrik Pedersen; Simon Elliott; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The crystalline solids aluminium nitride (AlN), gallium nitride (GaN) and indium nitride (InN), together with their alloys, are of huge interest in the semiconductor industry. Their bandgaps span an extensive range from 6.0 eV for AlN to 0.7 eV for InN, with GaN in between at a bandgap of 3. READ MORE

  4. 22. Engineering of metal microstructures : process-microstructure-property relationships for electrodeposits

    Author : Jens A. D. Jensen; Dieter Landolt; Linköpings universitet; []
    Keywords : ;

    Abstract : The relationships between growth-conditions, topography and microstructure, and physical properties of electrochemically deposited copper, nickel and zinc-iron alloys were studied. Growth was investigated while systematically varying process parameters such as electrolyte chemistry, type and concentration of additives, current density, and mass transport. READ MORE

  5. 23. Modelling and simulation of welding and metal deposition

    Author : Andreas Lundbäck; Jesper Hattel; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design; Material Mechanics; Materialmekanik;

    Abstract : Fusion welding is one of the most used methods for joining metals. This method has largely been developed by experiments, i.e. trial and error. READ MORE

  6. 24. Extraction of Metal Values : Thermodynamics of Electrolyte Solutions and Molten Salts Extraction Process

    Author : Xinlei Ge; Seshadri Seetharaman; Katsunori Yamaguchi; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrolyte solutions; activity coefficient; osmotic coefficient; freezing point depression; boiling point elevation; Materials science; Teknisk materialvetenskap;

    Abstract : Over the past centuries, a number of process routes for extraction of metal values from an ore or other resources have been developed. These can generally be classifiedinto pyrometallurgical, hydrometallurgical or electrometallurgical routes. READ MORE

  7. 25. 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
