    Sammanfattning : Metastable (Ti,Si)N alloy and TiN/SiNx multilayer thin solid films as well as SiNx/TiN surfaces have been explored. Cubic Ti1-xSixN (0≤x≤0. LÄS MER

  3. 2. Materials Design from First Principles : stability and magnetism of nanolaminates

    Författare :Martin Dahlqvist; Johanna Rosén; Nicola Spaldin; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : In this thesis, first-principles calculations within density functional theory are presented, with a principal goal to investigate the phase stability of so called Mn+1AXn (MAX) phases. MAX phases are a group of nanolaminated materials comprised of a transition metal (M), a group 12-16 element (A), and carbon or nitrogen (X). LÄS MER

  4. 3. Synthesis and characterization of Mo-based nanolaminates

    Författare :Rahele Meshkian; Johanna Rosén; Árni Sigurður Ingason; Hans Högberg; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Mn+1AXn (MAX) phases are nanolaminated compounds based on a transition metal (M), a group A element (A), and carbon or/and nitrogen (X), which exhibit a unique combination of ceramic and metallic properties. Mo-based MAX phases are among the least studied, despite indication of superconducting properties and high potential for fabrication of the grapheneanalogous 2D counterpart, Mo2C MXene. LÄS MER

  5. 4. Magnetic properties of hard-soft amorphous nanolaminates

    Författare :Parul Rani; Gabriella Andersson; Petra Jönsson; Kostas Sarakinos; Erik Wahlström; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Amorphous Thin Film; Soft Hard Multilayers; Combinatorial Sputtering; Magnetism; Rigid-Exchange coupling; First-Order Reversal Curve; Fysik; Physics;

    Sammanfattning : Amorphous magnetic thin film heterostructures and multilayers are often used in data storage as well as spintronic devices. Spintronics will help the next generation of nano-electronic devices to increase their memory and processing power and reduce their power consumption. LÄS MER

  7. 5. Synthesis and characterization of two- and three-dimensional nanolaminated carbides

    Författare :Quanzheng Tao; Johanna Rosén; Per O A Persson; Amit Keren; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis is focused towards the synthesis and characterization of novel nanolaminated materials in primarily bulk (powder) form. Of particular interest is magnetic materials, or laminates that can be used as precursor for two-dimensional (2D) materials. LÄS MER
