摘要
In this paper we report the extraction of carrier lifetimes of GH-SIC P-i-N rectifiers under high-level injection from reverse recovery measurements. Studies of carrier lifetime at different operating temperatures and injection levels show that the Auger recombination is the dominant process during high-level injection. An Auger coefficient of 2.5 similar to 3.5 x 10(-29)cm(6)/s has been estimated from the extracted high-level recombination lifetime.
