Effect of impurity impact ionization on the dynamic characteristics of 4H-SiC $p^+$–$n$–$n^+$ diodes at low temperatures (77 K)

Abstract:
The low temperature (77 K) transient switch-on characteristics of 4H-SiC $p^+$–$n$–$n^+$ diodes are measured in the pulse mode. Using a simple analytical model, the effect of impurity breakdown in a heavily doped $p^+$-type emitter on the current rise dynamics after applying high-amplitude forward-bias pulses to the diode is explained.
