According to the approach of Beattie and Landsberg [31], the intrinsic Auger lifetime is calculated by perturbation method. The perturbation operator of Auger mechanism, i.e., of Coulomb interaction of two electrons, is calculated by subtracting Hartree-Fock single-electron Hamiltonian from the complete Hamiltonian of the system (and actually the simplest Hamiltonian that still sees the Coulomb interaction of the Auger process). It has the form of a screened Coulomb potential... 

There are various approximations in literature for intrinsic Auger lifetime for the CCCH process for the case of parabolic bands and nondegenerate semiconductor. The most often met is... 

The ration of intrinsic Auger lifetimes for Auger 1 and Auger 7 processes is approximately [41]... 

The influence of electric field to the increase of Auger generation can be calculated starting from the Beattie-Landsberg expression for Auger 1 intrinsic recombination lifetime x ... 

It is a characteristic feature of inner-shell excitation in free atoms that the series limits are broadened by core-lifetime or Auger effects (see section 8.32), which truncate the series beyond the first few members, giving rise to intrinsically unresolvable upper members and a lowering of the ionisation threshold below the series limit. This purely atomic effect, which results in a quasicontinuous region below the onset of the true continuum associated with a deep inner shell excitation threshold, allows an internal density of states to be constructed, whose properties (illustrated in fig. 11.1) have been studied both theoretically and experimentally for free atoms [596]. 

Interband Auger recombination had been thought to be insignificant in Pbj Snj(Te alloys [4.7], but the very recent theory by Emtage casts doubt upon that assumption [4.39]. However, in this chapter we have assumed that only radiative recombination need be considered as an intrinsic lifetime-limiting mechanism. Melngailis and Harman have calculated an expression for the radiative from which we can determine using (4.31) ... 

Carrier recombination in n-type Hgg gCdo jTe has been studied in detail by Kinch et al. [4.13] at temperatures high enough for trapping effects to be negligible. They found that the measured lifetime is limited by the interband Auger mechanism in the intrinsic range rather than by direct radiative...
