  2. 1. Color Centers in Semiconductors for Quantum Applications : A High-Throughput Search of Point Defects in SiC

    Author : Joel Davidsson; Igor A. Abrikosov; Rickard Armiento; Viktor Ivády; Giulia Galli; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; point defects; color centers; high-throughput; photoluminescence; zero phonon line; SiC;

    Abstract : Point defects in semiconductors have been and will continue to be relevant for applications. Shallow defects realize transistors, which power the modern age of information, and in the not-too-distant future, deep-level defects could provide the foundation for a revolution in quantum information processing.

  4. 2. Studies of Topological Superconductors via Defects

    Author : Oladunjoye Awoga; Annica Black-Schaffer; Pascal Simon; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Abstract : Defects from impurities, edges, junctions or domain walls have local detrimental effects on the superconducting state. Defects are also important in topological superconductors, and useful in studying the properties of the superconducting order parameter. READ MORE

  5. 3. Robotic in-line quality inspection system for Zero-Defect Manufacturing : Requirements and Challenges

    Author : Victor Azamfirei; Yvonne Lagrosen; Anna Granlund; Foivos Psarommatis; Rikard Söderberg; Mälardalens universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; automation; industrial robot; sensor; in-line quality inspection; Zero-Defect Manufacturing ZDM ; Innovation and Design; innovation och design;

    Abstract : The modern manufacturing paradigm is characterised by an increased level of competition, growing demand for customisable or one-of-a-kind products, and stricter sustainability requirements. To maintain their competitiveness, manufacturing companies must adapt their processes frequently and efficiently while providing high-quality products. READ MORE

  6. 4. Influence of defects and impurities on the properties of 2D materials

    Author : Soumyajyoti Haldar; Biplab Sanyal; Olle Eriksson; Torbjörn Björkman; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; 2D Materials; Defects on 2D materials; Impurities on 2D materials; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Abstract : Graphene, the thinnest material with a stable 2D structure, is a potential alternative for silicon-based electronics. However, zero band gap of graphene causes a poor on-off ratio of current thus making it unsuitable for logic operations. This problem prompted scientists to find other suitable 2D materials.

  7. 5. Laser welding and cladding : the effects of defects on fatigue behaviour

    Author : Md. Minhaj Alam; Stewart Williams; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Manufacturing Systems Engineering; Produktionsutveckling;

    Abstract : The thesis focuses on weld defects in laser processed materials (for laser welding, laser hybrid arc welding and laser cladding) and their effect on the fatigue life of components. Component properties were studied with particular emphasis on the macro and micro surface geometry, weld defects and clad defects. READ MORE
