  1. 1. Growth and Phase Stability Studies of Epitaxial Sc-Al-N and Ti-Al-N Thin Films

    Författare :Carina Höglund; Lars Hultman; Jens Birch; Daniel Gall; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : ¨This Thesis treats the growth and characterization of ternary transition metal nitride thin films. The aim is to probe deep into the Ti-Al-N system and to explore novel Sc-Al-N compounds. Thin films were epitaxially grown by reactive dual magnetron sputtering from elemental targets onto single-crystal substrates. LÄS MER

  3. 2. Design of Transition-Metal Nitride Thin Films for Thermoelectrics

    Författare :Sit Kerdsongpanya; Per Eklund; Björn Alling; Gunilla Wingqvist; Lars Hultman; Daniel Gall; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Thermoelectric devices are one of the promising energy harvesting technologies, because of their ability to convert heat (temperature gradient) to electricity by the Seebeck effect. Furthermore, thermoelectric devices can be used for cooling or heating by the inverse effect (Peltier effect). LÄS MER

  4. 3. Toughness Enhancement in Hard Single-Crystal Transition-Metal Nitrides : V-Mo-N and V-W-N Alloys

    Författare :Hanna Kindlund; Lars Hultman; Jens Birch; Daniel Gall; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Transition-metal nitrides are known for their high hardness, good wear resistance, high-temperature stability, and chemical inertness. Because of these properties, they are extensively used in many industrial applications, notably as protective wear, erosion, and scratch resistant coatings, which are often subjected to high thermo-mechanical stresses.
