The role of defects and dimensionality in influencing the charge, capacitance, and energy storage of graphene and 2D materials

Nanotechnology Reviews, 2017
The inevitable presence of defects in graphene and other two-dimensional (2D) materials influences the charge density and distribution along with the concomitant measured capacitance and the related energy density.

Towards understanding the structure and capacitance of electrical double layer in ionic liquids [PDF]

, 2008
In order to understand basic principles of the double layer formation in room temperature ionic liquids, we have performed Molecular Dynamic simulations for a simplified system: dense assembly of charged Lennard-Jones spheres between charged walls.

Bandgap‐Engineered AlGaAs/GaAs Heterostructures for Wavelength‐Selective Dual‐Polarity Photoelectrochemistry

Advanced Functional Materials, EarlyView.
Bandgap‐engineered AlGaAs/GaAs heterostructures exhibit wavelength‐selective dual‐polarity photoelectrochemistry, switching from photocathodic to photoanodic response depending on excitation wavelength. The polarity transition is governed by band‐selective absorption, built‐in electric‐field‐driven carrier transport, and interfacial charge‐transfer ...

Influence of the Electrolyte pH on the Double Layer Capacitance of Polycrystalline Pt and Au Electrodes in Acidic Solutions

ChemElectroChem
A deeper understanding of electrified solid/liquid interfaces of polycrystalline materials is crucial for optimizing energy conversion and storage devices, such as fuel cells, electrolyzers, and supercapacitors. After more than a century of research, the

Ionic liquid near a charged wall : structure and capacitance of electrical double layer [PDF]

, 2008
We study the effects of ion size asymmetry and short-range correlations on the electrical double layer in ionic liquids: we perform molecular dynamics simulations of a model ionic liquid between two "electrodes" and calculate the differential capacitance

Interface Effects in Ultrathin Silicon on Insulator Films

Advanced Functional Materials, EarlyView.
This work establishes a systematic framework to discriminate how bulk and interface phenomena affect charge transport in ultrathin P‐doped silicon‐on‐insulator (SOI) films. For Si films below 15 nm, electrical characterization demonstrates that interface states drive charge transport, shifting the metal‐insulator transition (MIT) critical dopant ...

Effects of Boron-Incorporation in a V-Containing Zr-Based AB2 Metal Hydride Alloy

Batteries, 2017
In this study, boron, a metalloid element commonly used in semiconductor applications, was added in a V-containing Zr-based AB2 metal hydride alloy. In general, as the boron content in the alloy increased, the high-rate dischargeability, surface exchange
