ABSTRACT

By Monte Carlo simulations, Ries et al. (1983,1984) showed that the decay of the geminate recombination rate follows a t~x law, where x ^ 3/2. Both the exponent and the initial recombination rate were dependent upon the thermalization distance. When the final recombination step was impeded by an energy barrier, the recombination kinetics could be described by an exponential time dependence. Results of the simulations show significant deviations from the asymptotic forms of the solutions of Hong and Noolandi. Within the time domain of experimental relevance, the simulated recombination rates are significantly larger.
