Kinetics of Defect Accumulation and Recombination: II. Diffusion‐Controlled Defect Annihilation

In the present part of the paper the kinetic equations, derived in its first part and taking into account the spatial correlations of both, the similar and dissimilar defects, are applied to both the theory of diffusion‐controlled defect annihilation, A + B → 0, and energy transfer, A + B → A. It is shown that only taking into account the correlation of the similar defects, one can describe the transition from bimolecular to monomolecular kinetics if the correlation within initially created Frenkel pairs varies from a random distribution to a very strong one. Even for the case of initially uncorrelated pairs of dissimilar defects an annihilation stimulates with time the creation of the similar defect correlation. In turn, it results in the deviation from the wellknown constant of quasi‐steady state recombination, k₀ = 4πDR_a. The present theory is compared with analogous theories by Waite and Antonov‐Romanovskii.
