  1. 31. Synthesis and Characterization of Multifunctional Carbide- and Boride-based Thin Films

    Författare :Nils Nedfors; Ulf Jansson; Witold Gulbinski; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; thin film; coating; magnetron sputtering; nanocomposite; boride; carbide; electrical properties; mechanical properties; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

    Sammanfattning : This thesis present research on synthesis, microstructure, and properties of carbide- and boride- based thin films. The films have been synthesized by dc magnetron sputtering, and their microstructures have been characterized mainly by X-ray photoelectron spectroscopy (XPS), X-ray diffraction, and transmission electron microscopy.
