  1. 1. Theoretical and experimental studies of ternary and quaternary nitrides for machining and thermoelectric materials

    Författare :Robert Pilemalm; Per Eklund; Sergei I Simak; Biplap Sanyal; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; materials science; thin film physics; nitrides; machining; thermoelectrics; materialvetenskap; tunnfilmsfysik; nitrider; metallbearbetning; termoelektricitet;

    Sammanfattning : Nitrides are used as coatings and thin films for a wide range of applications. The study and use of nitrides in the recent decades have shifted towards ternary, quaternary or even higher order (complex) nitrides. LÄS MER

  3. 2. A First-Principles Study of Highly Anharmonic and Dynamically Disordered Solids

    Författare :Johan Klarbring; Sergei Simak; Per Eklund; Claudine Katan; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis is a first-principles theoretical investigation of solid materials with high degrees of anharmonicity. These are systems where the dynamics of the constituent atoms is too complex to be well-described by a set of uncoupled harmonic oscillators. LÄS MER

  4. 3. Influence of stresses and impurities on thermodynamic and elastic properties of metals and alloys from ab initio theory

    Författare :Olga Vekilova; Igor Abrikosov; Sergei Simak; Björn Winkler; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Stresses and impurities may influence elastic properties, phase stability and magnetic behavior of metals and their alloys. A physical understanding of this influence is of great importance to both fundamental science and technological applications. LÄS MER
