Percolation description of charge transport in amorphous oxide semiconductors [PDF]

open access: yesPhysical Review B, 2019
The charge transport mechanism in amorphous oxide semiconductors (AOS) is a matter of controversial debates. Most theoretical studies so far neglected the percolation nature of the phenomenon.

Charge transport variation from Bloch–Grüneisen to Mott variable range hopping and transport change due to hydrogenation in Palladium thin films

open access: yesScientific Reports, 2021
We report a systematic investigation of the differences in charge transport mechanism in ultra-thin nano-island like films of palladium with thickness varying between 5 nm and 3 nm. The thicker films were found to be metallic in a large temperature range

Structural-disorder-driven critical quantum fluctuation and localization in two-dimensional semiconductors

open access: yesNature Communications, 2023
Quantum fluctuations of wavefunctions in disorder-driven quantum phase transitions (QPT) exhibit criticality, as evidenced by their multifractality and power law behavior. However, understanding the metal-insulator transition (MIT) as a continuous QPT in

Dielectric properties, polarization process, and charge transport in granular (FeCoZr)x(Pb(ZrTi)O3)(100−x) nanocomposites near the percolation threshold

open access: yesAIP Advances, 2022
This paper presents the research of dielectric properties of (FeCoZr)x(Pb(ZrTi)O3)(100−x) granular metal–dielectric nanocomposites below the percolation threshold.

Anomalous Charge Transport in Conjugated Polymers Reveals Underlying Mechanisms of Trapping and Percolation

open access: yesACS Central Science, 2016
While transport in conjugated polymers has many similarities to that in crystalline inorganic materials, several key differences reveal the unique relationship between the morphology of polymer films and the charge mobility. We develop a model that directly incorporates the molecular properties of the polymer film and correctly predicts these unique ...

Chiral transition and monopole percolation in lattice scalar QED with quenched fermions [PDF]

open access: yes, 1997
We study the interplay between topological observables and chiral and Higgs transitions in lattice scalar QED with quenched fermions. Emphasis is put on the chiral transition line and magnetic monopole percolation at strong gauge coupling.

Unveiling Charge‐Transport Mechanisms in Electronic Devices Based on Defect‐Engineered MoS2 Covalent Networks

open access: yesAdvances in Materials, 2023
Device performance of solution‐processed 2D semiconductors in printed electronics has been limited so far by structural defects and high interflake junction resistance.

Competing charge trapping and percolation in core-shell single wall carbon nanotubes/ polyaniline nanostructured composites

open access: yes, 2020
Core-shell single wall carbon nanotube (SWCNT)/ polyaniline (PANI) nanocomposites were chemically synthesized and their structural, morphological, and dielectric properties were investigated as a function of the nanofiller content. X-ray diffraction (XRD)

Charge percolation in redox-active thin membrane hybrids of mesoporous silica and poly(viologens).

open access: yesPhysical Chemistry, Chemical Physics - PCCP, 2019
This work reports the fabrication of redox-active films of oligomeric and molecular viologens and mesoporous silica via the infiltration method. Pore-ellipsometry and UV-vis confirm that low-molecular-weight poly(viologens) in solution are able to enter ...

Design Principles for High-Capacity Mn-Based Cation-Disordered Rocksalt Cathodes [PDF]

open access: yes, 2020
Mn-based Li-excess cation-disordered rocksalt (DRX) oxyfluorides are promising candidates for next-generation rechargeable battery cathodes owing to their large energy densities, the earth abundance, and low cost of Mn.
