  1. 1. Fabrication and Characterization of Si-on-SiC Hybrid Substrates

    Författare :Ling-Guang Li; Jörgen Olsson; Örjan Vallin; Stefan Bengtsson; Uppsala universitet; []
    Nyckelord :hydrophilic wafer bonding; silicon on silicon carbide; hybrid substrate; oxygen out-diffusion; Engineering Science with specialization in Electronics; Teknisk fysik med inriktning mot elektronik;

    Sammanfattning : In this thesis, we are making a new approach to fabricate silicon on insulator (SOI). By replacing the buried silicon dioxide and the silicon handling wafer with silicon carbide through hydrophilic wafer bonding, we have achieved silicon on crystalline silicon carbide for the first time and silicon on polycrystalline silicon carbide substrates at 150 mm wafer size.

    Sammanfattning : This thesis consider aspects concerning the transport, distribution and incorporation of Na in Cu(In,Ga)Se2 absorber layers for thin film solar cells. The influence of Na on the growth of Cu(In,Ga)Se2 layers has been studied, as well as the influence on the device performance. LÄS MER

  4. 3. Thick and Thin Ti2AlC Coatings

    Författare :Jenny Frodelius; Lars Hultman; Per Eklund; Hans Högberg; Lars Nyborg; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : This Thesis explores the deposition techniques of magnetron sputtering and high velocity oxy-fuel (HVOF) spraying for Ti2AlC as a promising high-temperature material. Magnetron sputtering aims at producing thin (≤1 μm) Ti2AlC films of high crystal quality for use as a model system in understanding the material’s basic properties. LÄS MER
