Transient and dc photoconductivity measurements are presented for two low-mobility dielectrics, poly (vinylidene fluoride) and polyethylene terephthalate. In each case, the data are analyzed using the present models for dispersive transport, and the inadequacies of these theories when applied to these low-mobility dielectrics are illustrated. In this paper we report an anomalously small transient photoresponse in poly (vinylidene fluoride); from our analysis, we attribute this result to the dispersive transport limited drift mobility in this material. Polymer structure and electric field contributions to the radiation-induced conductivity in these dielectrics are also discussed.
