  5. 5. Carrier Lifetime Relevant Deep Levels in SiC

    Författare :Ian Don Booker; Einar Sveinbjörnsson; Erik Janzén; Anthony Peaker; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Silicon carbide; Deep level transient spectroscopy; Deep level; Carrier lifetime; Time-resolved photoluminescence;

    Sammanfattning : Silicon carbide (SiC) is currently under development for high power bipolar devices such as insulated gate bipolar transistors (IGBTs). A major issue for these devices is the charge carrier lifetime, which, in the absence of structural defects such as dislocations, is influenced by point defects and their associated deep levels.
