Impurity-impurity recombination in a random potential of charged impurities
Zhdanova N. G. , Kagan M. S. , Landsberg E. G. , Petrishchev V. V.
The random Coulomb potential of charged impurities affects the impurity-impurity recombination of a neutral donor and a repulsive acceptor in Ge. The coefficient of impurity-impurity recombination depends on the temperature and the illumination intensity, because impurity levels are spread out by the random potential.
