摘要：
A Monte Carlo calculation is presented of the range-dependent survival probability of an initially randomly distributed electron-hole population recombining according to a nearest-available-neighbor rule. It confirms a previous prediction of an asymptotic power-law behavior in three dimensions, with exponent minus 3/2. The distribution of surviving electrons and holes in the asymptotic region takes the form of two interlacing electron and hole networks. The relevance of the nearest-available-neighbor recombination model as an approximation to real systems is discussed.
