| Center ionization accompanied by carrier localization at the center by virtue of a short-range or a long-range Coulomb attractive potential is discussed. The role of charge transfer states in recombination processes is described. The source of carrier attractive potential is explained and a simple theoretical model is presented allowing to predict the nature (either electron or hole attractive) of this potential. The probability of different possible recombination paths is also analyzed. |
