  1. 11. Multifunctional nanostructured Ti-Si-C thin films

    Författare :Per Eklund; Lars Hultman; Hans Högberg; G. Ramanath; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material physics with surface physics; Materialfysik med ytfysik;

    Sammanfattning : In this Thesis, I have investigated multifunctional nanostructured Ti-Si-C thin films synthesized by magnetron sputtering in the substrate-temperature range from room temperature to 900 °C. The studies cover high-temperature growth of Ti3SiC2 and Ti4SiC3, low-temperature growth of Ti-Si-C nanocomposites, and Ti-Si-C-based multi¬layers, as well as their electrical, mechanical, and thermal-stability properties.
