We have performed numerical analysis of the charge carrier transport in a specific molecularly doped
polymer using the multiple trapping model. The computations covered a wide range of applied electric
fields, temperatures and most importantly, of the initial energies of photo injected one-sign carriers
(in our case, holes). Special attention has been given to comparison of time of ...

We have performed Monte-Carlo simulations of the charge carrier transport in a model molecularly doped polymer using three most popular hopping theories (the dipolar glass model, the Gaussian disorder model, and an intermediate between them) in a wide range of applied electric fields and temperatures. Time of flight transients have been computed and analyzed in ...

Abstract—Transient current curves in a polar molecularly doped polymer for subsurface and bulk generations of charge carriers are compared. No transformation of the horizontal plateau on the former to the curve predicted by the diffusion and drift theory was found, contrary to expectations for quasi-equilibrium transport conditions. This behavior indicates a nonequilibrium character of the ...

We have examined the Poole-Frenkel mobility field dependence in a molecularly doped polymer (MDP) both experimentally and theoretically trying to separate two physically different contributions to this phenomenon, one constituting a real physical effect and the other arising from the fact that the charge carrier transport in MDP is not fully equilibrated. The former is ...

We have compared time-of-flight curves predicted by hopping and multiple trapping models with the Gaussian and exponential site/trap energy distributions, fitting Monte-Carlo predictions of the former with numerical calculations of the latter in a wide time domain using logarithmic coordinates lg j–lg t for the characterization of current shapes and an estimation of transit times. As a ...

Abstract — The transient current curves for a polar molecularly doped polymer were compared for the near? surface and bulk generation of charge carriers. The horizontal plateau on the first curve was expected to trans? form into a tilted straight line under the quasiequilibrium transport conditions, but it did not. Instead, for bulk generation, the ...

Abstract—The general problems of the bimolecular recombination of charge carriers in molecularly doped polycarbonate are discussed. Experimental studies are performed via the transient radiationinduced conductivity method. Transientcurrent curves are numerically calculated via the multiple trapping model. The calculated and experimental curves are in good agreement. It is shown that the studied molecularly doped polymer undergoes ...

We present the results of Monte Carlo simulations of the charge carrier transport in a disordered molecular system containing spatial and energetic disorders using the dipolar glass model. Model parameters of the material were chosen to fit a typical polar organic photoconductor polycarbonate doped with 30% of aromatic hydrazone, whose transport properties are well documented ...

В статье рассмотрено теоретическое описание электронного транспорта в молекулярно допированных полимерах. В настоящей работе выполнено численное решение уравнений модели многократного захвата применительно к постановке идеализированного времяпролетного эксперимента. Проведенные расчетные данные позволяют существенно прояснить картину поведения переходных токов, измеряемых в процессе времяпролетного эксперимента в материалах с повышенным значением дисперсионного параметра, преодолевая тем самым ограничения, накладываемые классическим ...

Hole transport in PS and PC doped with low molecular-mass-dopants with dipole moments larger than 3D is investigated. Both near-surface and bulk charge-carrier generation techniques are used. There is good agreement between the experimentally measured values of hole mobility and the published data. It is shown that, for the investigated systems, the hole transport is ...

Transient current curves were recorded for polystyrene and polycarbonate doped with 15 wt % tritolylamine using both surface and volume charge carrier generation. The multiple trapping model was used to perform numerical calculations of time-of-flight curves for the published Gaussian disorder model parameters. The calculation results were compared with the experimental data. It was shown ...

The shape of time-of-flight curves in the mode of subsurface irradiation of samples with lowenergy electrons is analyzed for free_standing films of a typical molecularly doped polymer of different thicknesses (11–45 μm). Special attention is paid to comparison of curves registered for both sides of the samples. The data confirm the hypothesis that the defective ...

Theoretical and experimental studies of the carrier transport in molecularly doped polymers (MDPs) have been reported. Theoretical analysis uses the multiple trapping (MT) model with an exponential and Gaussian trap distributions. Experimental technique is based on an electron gun technology enabling one to conduct time of flight measurements using the surface and the bulk carrier ...

The effect of preliminary electron beam irradiation on hole transport in a molecularly doped polymer was studied with the use of the time of flight technique in the radiation_induced mode. Specimens that exhibit a plateau on their time of flight curves were selected for the study, since they suggest the occurrence of quasi equilibrium transport ...

The correlated disorder model (CDM) has been proposed as a theory of charge transport in molecularly doped polymers (MDPs). Recently a test of the CDM was proposed: it was predicted that the dipolar disorder energy can be obtained from the slope of the log of the mobility versus square root of the electric field (the ...
