## Theoretical analysis of the charge carrier transport in thin layers of disordered materials with exponential band tail states

Computational Materials Science. 2023. Vol. 230. Article 112463.

Analytic solutions of the convection–diffusion equation (CDE) have been obtained in the case of the exponential band tail states for a reflecting front electrode. Analytic expressions for the transient current density in time-of-flight (TOF) experimental conditions have been obtained. An assessment of the distortion by diffusion has been made for a data analysis of the common TOF method. A new method for calculating a charge carrier mobility and other transport parameters in thin layers of disordered materials has been proposed using the weak-field TOF experiments. The obtained results can provide the use of TOF method for optimizing the characteristics and designing thin-film electronic devices.

Keywords: charge carrier transport

We study the process of a nucleon separating from an atomic nucleus from the mathematical standpoint
using experimental values of the binding energy for the nucleus of the given substance. A nucleon becomes
a boson at the instant of separating from a fermionic nucleus. We study the further transformations of
boson and fermion states of separation in a ...

We study regularization scheme dependence of beta-function for sigma models with two-dimensional target space. Working within four-loop approximation, we conjecture the scheme in which the beta-function retains only two tensor structures up to certain terms containing zeta_3. Using this scheme, we provide explicit solutions to RG flow equation corresponding to Yang-Baxter- and lambda-deformed SU(2)/U(1) sigma ...

We demonstrate that magnetoresistance of creeping charge-density waves in the quasi-one-dimensional
conductor o-TaS 3 changes its character from a negative parabolic at T 10 K, where it obeys the 1/T 2 law
to a weakly temperature-dependent negative nearly linear one at lower temperatures. The dominant contribution into the negative parabolic magnetoresistance comes from magnetic field induced ...

To date, a number of lantibiotics have been shown to use lipid II — a highly conserved peptidoglycan precursor in the cytoplasmic membrane of bacteria — as their molecular target. The α-component (Lchα) of the two-component lantibiotic lichenicidin (Lchα), previously isolated from the Bacillus licheniformis VK21 strain, seems to contain two putative lipid II binding ...

In this work, we present for the first time the Lyman α intensities measured by Voyager 1/UVS in 2003–2014 (at 90–130 AU from the Sun). During this period Voyager 1 measured the Lyman α emission in the outer heliosphere at an almost fixed direction close to the upwind (i.e.“ toward the interstellar flow). The data show an unexpected behavior in 2003–2009: the ...

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 ...

states when N receivers are separately located. In this report, we propose optical designs that can
perform sequential state discrimination of two coherent states. For this purpose, we consider not

probabilities. Since ...
