About the microscopic picture of the hole transport in dehdoped polycarbonate
P. 557–558.
Our approach to the problem of charge carrier transport in homogeneous polymers assumes carrier hopping on a densely packed manifold of transport (hopping) centers retaining the short-range order of the respective single crystal. The central idea, which distinguishes it from the Bassler’s disorder theory, is that the energy scatter concerns only a small fraction of hopping centers, which begin to act as traps. The majority of isoenergetic centers build up a transfer band with microscopic mobility µ0 equal to that in the respective single crystal. The origin of the energy scatter (and traps themselves) is ascribed to the elementary voids of the fluctuation free volume forming an association with the normal hopping centers.

CsSnI3 perovskite is a thin-film semiconductor with high intrinsic conductivity for various device applications (thermoelectric, photovoltaics, etc.). Stoichiometric CsSnI3 has high-density defects and structural imperfections affecting device performance. In this work, we made an investigation on A-site cation engineering to evaluate the correlation between structural and transport parameters for effective operation in rectifying devices. Here, ...

Gayduchenko I., Prudkoglyad V., Kuntsevich A., Physical Review B: Condensed Matter and Materials Physics 2024 Vol. 109 No. 16 Article L161401
Despite decades of intensive studies, some aspects of charge transport through carbon nanotubes (CNTs) remain poorly understood. Here, we explore the transport properties of field-effect devices based on metallic CNTs, where the density of states is supposed to be constant and a field effect is not anticipated. The observed current-voltage characteristics are qualitatively different from ...

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 ...

Numerical calculations have been performed on the time of flight transients predicted by a newly developed model describing consistently the radiation-induced conductivity of common insulating polymers under both pulsed and continuous irradiation. The model differs substantially from the conventional multiple trapping formalism based on an exponential trap distribution by the presence of additional deep traps distributed in energy ...

Quantum dot (QD) solids represent a new type of condensed matter drawing high fundamental and applied interest. Quantum confinement in individual QDs, combined with macroscopic scale whole materials, leads to novel exciton and charge transfer features that are particularly relevant to optoelectronic applications. This Perspective discusses the structure of semiconductor QD solids, optical and spectral ...

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 ...

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 ...
