    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Surface Acoustic Waves; MXene; i-MXene; Supercapacitor;

    Abstract : Climate Change is believed to be the greatest global challenge and on its forefront is the topic of energy. While being of extreme importance, debates over energy have become a normality. READ MORE

  4. 7. Cathodic Arc Synthesis of Ti-Si-C-N Thin Films : Plasma Analysis and Microstructure Formation

    Author : Anders Eriksson; Johanna Rosén; Lars Hultman; Arutiun Ehiasarian; Linköpings universitet; []
    Keywords : ;

    Abstract : This Thesis explores the arc deposition process and films of Ti-Si-C-N, inspired by the two ternary systems Ti-Si-N and Ti-C-N, both successfully applied as corrosion and wear resistant films. The correlation between cathode, plasma, and film properties are studied for a comprehensive view on film formation. READ MORE

  5. 8. Cathodic Arc Synthesis of Ti-Si-C-N Thin Films from Ternary Cathodes

    Author : Anders Eriksson; Johanna Rosén; Claudia Walter; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : Cathodic arc deposition is a powerful technique for thin film synthesis, associated with explosive phase transformations resulting in an energetic and highly ionized plasma. This Thesis presents film growth through arc deposition from compound cathodes of Ti3SiC2, providing source material for plasma and films rich in Si and C. READ MORE
