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 ...

We have investigated the radiation-induced conductivity (RIC) in Kapton-like polymers in which it increases with an accumulating dose at large dose rates and long irradiation times. Such a behavior is very useful for spacecraft applications as it allows mitigating the spacecraft charging problems. Also, we studied ordinary polymers whose RIC steadily falls after reaching an ...

Charge transport in amorphous semiconductors having spatially correlated exponential density of states (DOS) has been considered for the arbitrary behavior of the correlation function of random energies. Average carrier velocity is exactly calculated for the quasi-equilibrium (nondispersive) transport regime. For the symmetric exponential DOS with exponential tails for low and high energies and non-positive correlation ...

Organometal triiodide perovskites are promising, high-performance absorbers in solar cells. Considering the perovskite as a thin film absorber, we solve transport equations and analyse the efficiency of a simple heterojunction configuration as a function of electron–hole diffusion lengths. We found that for a thin film thickness of ~1 micron the maximum efficiency of ~31% could ...

Two techniques of manufacturing a nanocomposite based on a complex of polyaniline with polymer acid and graphene are proposed. The electric conductivity of thin nanocomposite layers is higher than that of a polymer complex of polyaniline and strongly depends on the degree of oxidation of graphene.

Based on the random phase approximation, we develop a molecular theory of self-coacervation in zwitterionic polymer solutions. We show that the interplay between the volume interactions of the monomeric units and electrostatic correlations of charged groups on a polymer backbone can result in liquid-liquid phase separation (self-coacervation). We analyse the behavior of the coacervate phase ...
