“…Also, an important advantage of an ionizing radiation (fast electrons in our case) is the possibility to exploit radiation chemistry results for assessing the concentration of free carriers escaping recombination in geminate pairs [21]. To obtain RIC and TOF data, which would allow an unequivocal interpretation, one needs to carry out measurements in the small signal regime so that the applied field remains unperturbed and no carrier loss to bimolecular recombination occurs.…”

A critical analysis of the existing time-of-flight (TOF) data in poly(Nvinylcarbazole) (PVK) proves that these are highly controversial with claims and counterclaims about charge carrier transport (dispersive versus Gaussian). It is felt that the TOF method taken alone is incapable of resolving the standing dilemma. As a final means to resolve it, we propose a combination of two varieties of the TOF technique using both sheet-like and uniform carrier generation modes in conjunction with radiation-induced conductivity measurements. All three techniques are realized using the ELA-50 electron gun facility. To demonstrate the effectiveness of our approach we report experimental data for PVK, which show that carrier transport in this polymer is indeed dispersive. Evidence is presented substantiating the gross interference the surface traps could exert on the shape of a TOF transient. As a result, a preflight part of the TOF signal should not be used for parameter evaluation.

“…Here β = 1/k B T , k B being the Boltzmann constant; T is the absolute temperature. Hummel [3] made a further generalization using the partially reflecting boundary condition instead of the Smoluchowski one which was used by Debye. In the case of Coulomb interparticle potential, the Hummel rate constant reads…”

The first correction to the total flux of charged particles into a sink including the mutual influence of the other sink for the system of two charged static sinks is obtained. It turns out that the correction is negative for a high intrinsic rate constant and positive otherwise. It is shown that for attractive reactants the diffusive interaction effect may be neglected even in the case of fully diffusion-controlled reactions for large enough values of the Onsager length. Moreover the monopole approximation formula is suggested to describe the diffusive interaction between closely located sinks.
