Теоретическое описание электронного транспорта в гомо- и молекулярно допированных полимерах
Химия высоких энергий. 2011. Т. 45. № 5. С. 437-444.
The general aspects of electron transport in disordered organic media (polymers, organic glasses, molecularly doped polymers) are considered. A critical analysis of experimental results and their interpretation in terms of basic theoretical models and experimental methods used in research in this area is presented. Particular attention is given to the comparative analysis of the data obtained by the time-of-flight technique and in studying the radiation conductivity of polymers, in particular, to the possibility of describing the conductivity data in terms of the Gaussian disorder model.

Structural, magnetic and magnetotransport properties of (Bi1-xEux)2Se3 thin films have been studied experimentally as a function of Eu content. The films were synthesized by MBE. It is demonstrated that Eu distribution is not uniform, it enter quint-layers forming inside them plain (pancake-like) areas containing Eu atoms, which sizes and concentration increase with the growth of Eu content. Positive ...

We report the study of transport and magnetic properties of the YbB6–δ single crystals grown by inductive zone melting. A strong disparity in the low temperature resistivity, Seebeck and Hall coefficients is established for the samples with the different level of boron deficiency. The effective parameters of the charge transport in YbB6–δ are shown to ...

The mechanism of charge transport in molecularly doped polymers has been the subject of much discussion over the years. In this paper, data obtained from a new experimental variant of the time-of-flight (TOF) technique, called TOF1a, are compared to the predictions of a two-layer multiple trapping model (MTM) with an exponential distribution of traps. In ...

Проведено исследование временной зависимости переходного тока в ПС в режиме малого сигнала как на этапе его возгорания, так и на этапе спада при нескольких значениях напряженности приложенного электрического поля и дозы предварительного облучения. Показано, что хотя радиационная электропроводность ПС и определяется в значительной степени свободными носителями заряда, но учет затянутости процесса термополевой диссоциации геминальных пар ...

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 ...

Показано, что при комнатной температуре дисперсионный транспорт дырок в поликарбонате, до-пированном 30 мас. % ароматического гидразона ДЭШ, в интервале времен наблюдения до 1с не зависит от присутствия в его объеме заряженных центров в концентрации 6 1017-6 1019 м-3. Влияние дозы излучения за импульс на времяпролетную кривую обусловлено протеканием бимолекулярной рекомбинации. Оба этих результата полностью согласуются ...

Exploring life cycles of fungi is insightful for understanding their basic biology and can highlight their ecology. Here, we dissected the sexual and asexual life cycles of the obligate alkalophilic ascomycete Sodiomyces alkalinus that thrives at extremely high pH of soda lakes. Sodiomyces alkalinus develops acremonium-type asexual sporulation, commonly found in ascomycetous fungi. However, the ...

In this short review, we first discuss the results, which are mainly devoted to the generalizations of the famous Kohn–Luttinger mechanism of superconductivity in purely repulsive fermion systems at low electron densities. In the context of repulsive-U Hubbard model and Shubin–Vonsovsky model we consider briefly the superconducting phase diagrams and the symmetries of the order parameter ...

The framework of simple opposition realism - anti-realism is not enough to analyze the views on the reality of unobservable objects of quantum theory. First, it is necessary to distinguish between realism in relation to the theory and realism in relation to the theory’s objects. Secondly, realism in relation to classical objects can be combined, ...

This paper describes the surface environment of the dense plasma arcs that damage rf accelerators, tokamaks, and other high gradient structures. We simulate the dense, nonideal plasma sheath near a metallic surface using molecular dynamics (MD) to evaluate sheaths in the non-Debye region for high density, low temperature plasmas. We use direct two-component MD simulations ...
