  4. 4. Chloride-based Silicon Carbide CVD

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Henrik Pedersen; Erik Janzén; Anne Henry; Yaroslav Koshka; [2008]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES Chemistry; NATURVETENSKAP Kemi;

    Sammanfattning : Silicon carbide (SiC) is a promising material for high power and high frequency devices due to its wide bandgap, high break down field and high thermal conductivity. The most established technique for growth ofepitaxial layers of SiC is chemical vapor deposition (CVD) at around 1550 °C using silane, SiH4, and lighthydrocarbons e g propane, C3H8, or ethylene, C2H4, as precursors heavily diluted in hydrogen.
