Non-Langevin recombination in disordered dielectrics

Summary form only given. Negative transient RIC (radiation-induced conductivity) in short-circuited samples and nonmonotonic increase of radiation-induced space-charge density have recently been observed for polymers (low-density polyethylene, polytetrafluoroethylene) and inorganic dielectrics (MgO, CaF/sub 2/, AlN, LiNiO/sub 3/). These experimental data are analyzed, and it is shown that such a behavior of RIC and space-charge density can be caused by non-Langevin recombination with the recombination constant R smaller than the Langevin value R/sub o/. Possible mechanisms of recombination rate reduction have been considered.<
