The study involves the computational modeling of electrostatic discharge initiation in polymer materials utilized in space environment under low-temperature conditions. To address this challenge, experimental data on the radiation-induced electrical conductivity of polyimide and polyethylene terephthalate at reduced temperatures, have been employed. The simulation encompasses the evaluation of electric field intensity within polyimide and polyethylene ...

Three charge density waves (CDWs), two of which are formed above room temperature, are observed in the NbS3 monoclinic phase (NbS3-II). The charge density and mobility in the high-field limit have been determined for each of three CDWs in this work using the synchronization effect of CDWs in high-frequency fields. It has been found that the ...

Разработана методика и впервые получены достаточно полные данные по радиационной электропроводности полистирола при температуре 79K при импульсном и непрерывном воздействии электронов с энергией
50 keV. Показано, что радиационная электропроводность полистирола при температуре 79K, как и при
комнатной температуре определяется суммой двух компонент: мгновенной и задержанной. Обе компоненты
при 79K имеют значительно меньшие величины, чем при 298K. Полный сигнал ...

Radiation-induced conductivity in polyethyleneterephthalate and polyimide: Trap distribution effects
Tyutnev A., Vladimir Saenko, Evgenii Pozhidaev et al., Results in Physics 2021 Vol. 28 P. 104672-1–104672-6
Abstract
We have analyzed the radiation-induced conductivity in polyethyleneterephthalate (PET) and polyimide in terms of the recently developed semi-empirical model whose parameters have been determined numerically by a trial and error method based on our previously published results which have been shown to be correct with respect to such experimental limitations as recombination and current saturation. ...

Abstract—The electron transport is studied experimentally by measuring pulsed radiation-induced conductivity
in polyetheleneterephthalate under bulk irradiation of polymer films by fast electron pulses in a smallsignal
regime. Numerical simulation is performed using a multiple trapping model with an exponential energy
trap distribution. It is shown that, contrary to the reported interpretation of this phenomenon, there is no
electron extraction ...

Abstract: We have performed comparative numerical calculations using a multiple trapping (MT)
formalism with an exponential and an aggregate two-exponential trap distributions for describing
two mostly used experimental setups for studying the radiation-induced conductivity (RIC) and
the time-of-flight (TOF) effects. Computations have been done for pulsed and long-time
electron-beam irradiations in a small-signal regime. Predictions of these two approaches ...

Abstract: Electrical properties of the thin films of poly(arylene ether ketone) copolymers (co-PAEKs)
with the fraction of phthalide-containing units of 3, 5 and 50 mol% in the main chain were
investigated by using radiation induced conductivity (RIC) measurements. Transient current
signals and current-voltage (I-V) characteristics were obtained under exposing 20÷25 thick films of
the co-PAEKs to monoenergetic electron pulses ...

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 ...

Organic photovoltaic cells with a bulk heterojunction have been manufactured in which the photoactive layer consists of a mixture of bithiophene copolymer or related rotaxane with a fullerene derivative (PC70BM). The mobility of charge carriers in photoactive layers has been determined, the current–voltage characteristics of photovoltaic cells have been measured, and the energy level diagram ...

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 ...

Abstract—The charge-carrier transport model based on the multiple-trapping quasi-band theory with the Gaussian or exponential energy distributions of traps for the two-layer structure of the molecularly doped polymer sample is used to explain the experimentally observed constancy of the flat plateau on time-of-flight curves in a wide electric-field range. The constant shape of the time-of-flight ...

We reinvestigate the applicability of the concept of trap-free carrier transport in molecularly doped polymers and the possibility of realistically describing time-of-flight (TOF) current transients in these materials using the classical convection–diffusion equation (CDE). The problem is treated as rigorously as possible using boundary conditions appropriate to conventional time of flight experiments. Two types of ...

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 ...
