The purpose of this paper is the study of the impact ionization and the Auger recombination in Hg/sub 1-x/Cd/sub x/Te avalanche photodiodes, with 0.6 less than or equal to x less than or equal to 0.7. For x -- 0.7 it is shown that the spin orbit splitting is lower than the bandgap energy E/sub g/ so that impact ionization is initiated by holes from the split-off valence band. For x -- 0.6, -- E/sub g/, the rate of the Auger recombination is maximum, corresponding to a resonant impact ionization and to a maximum ratio k = US / where and US are, respectively, the impact ionization coefficient for electrons and holes.
