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

Scientific 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

Nature 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

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

Physical 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.

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

Advances 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.

Persistent X-ray photoconductivity and percolation of metallic clusters in charge-ordered manganites [PDF]

, 1998
Charge-ordered manganites of composition Pr1 − x(Ca1 − ySry)xMnO3 exhibit persistent photoconductivity upon exposure to X-rays. This is not always accompanied by a significant increase in the number of conduction electrons as predicted by conventional ...

Origin of multi-level switching and telegraphic noise in organic nanocomposite memory devices. [PDF]

, 2016
The origin of negative differential resistance (NDR) and its derivative intermediate resistive states (IRSs) of nanocomposite memory systems have not been clearly analyzed for the past decade.

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

Physical 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]

, 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.
