Abstract

We derived the impact ionization and Auger recombination rates within the framework of the six-band Kane model. The theory involves the electron distribution function and average electron energy which we computed using Monte Carlo simulations, along with the electron drift velocity. The excess carrier concentration is then determined from the balance equation. The results of the calculation are in good agreement with experimental data for HgCdTe at 77 K.
