  • Abstract
    The purpose of this paper is the study of the impact ionization and the Auger recombination in Hg1-xCdxTe avalanche photodiodes, with 0.6 \\leq x \\leq 0.7 . For x \\sim 0.7 it is shown that the spin orbit splitting Δ is lower than the bandgap energy Egso that impact ionization is initiated by holes from the Split-off valence band. For x \\sim 0.6, \\Delta \\sim E_{g} , the rate of the Auger recombination is maximum, corresponding to a resonant impact ionization and to a maximum ratio k = \\beta / \\alpha where α and β are, respectively, the impact ionization coefficient for electrons and holes.
