The band‐to‐band recombination rate of Auger recombination is derived by means of correlation functions of non‐equilibrium systems. In distinction to previous work where unscreened exchange interaction or static dielectric functions enter the corresponding matrix elements, the Coulomb as well as the exchange term of the Auger scattering amplitude is described by wave‐vector and frequency‐dependent dielectric functions. The results are compared qualitatively with existing calculations of Auger recombination.
