Electrochemistry experiments have established that the capacitance of electrode-electrolyte interfaces is much larger for good metals, such as gold and platinum, than for carbon-based materials. Despite the development of elaborate electrode interaction potentials, to date molecular dynamics simulations are not able to capture this effect. Here, we show that changing the width of the Gaussian charge distribution used to represent the atomic charges in gold is an effective way to tune its… Expand

A semiclassical Thomas-Fermi model to tune the metallicity of electrodes in molecular simulations.
The Thomas-Fermi model provides a very convenient framework to account for the screening of the electric field at the interface and differentiating good metals such as gold from imperfect conductors such as graphite, opening the door for quantitative predictions of the capacitive properties of materials for energy storage.

Water at an electrochemical interface--a simulation study.
It is shown how water is strongly attracted to and ordered at the electrode surface, different to the structure that might be imagined from continuum models of electrode interfaces, and the length scales over which ionic atmospheres fluctuate. Expand
Double Layer at the Pt(111)–Aqueous Electrolyte Interface: Potential of Zero Charge and Anomalous Gouy–Chapman Screening
It is concluded that the diffuse double layer structure at the Pt(111)‐electrolyte interface deviates significantly from the Gouy–Chapman theory in the sense that the electrostatic screening is much better than predicted by purely electrostatic mean‐field Poisson–Boltzmann theory. Expand
Polarization Effects in Dynamic Interfaces of Platinum Electrodes and Ionic Liquid Phases: A Molecular Dynamics Study
We outline molecular dynamics simulations of electrode–ionic liquid interfaces with explicit consideration of electronic polarization effects. For this, conventional molecular mechanics are extendedExpand
Effects of applied voltage on water at a gold electrode interface from ab initio molecular dynamics†
Controlled-potential simulations of the interfacial solvent dynamics provide a framework for further investigation of more complex or reactive species in the EDL and broadly for understanding electrochemical interfaces in situ. Expand

While the extent of ion adsorption is highly dependent on the electrolyte model (the polarizability of solvent and solutes, as well as the van der Waals radii), the effect of surface polarization on ion adsorbption is consistent throughout different electrolyte models. Expand
Influence of surface topology and electrostatic potential on water/electrode systems
We have used the classical molecular dynamics technique to simulate the ordering of a water film adsorbed on an atomic model of a tip of a scanning tunneling microscope approaching a planar metalExpand
A chemical potential equalization approach to constant potential polarizable electrodes for electrochemical-cell simulations.
The present approach clarifies the physical meaning of the total energy of a system that includes classical polarizable electrodes, which is important in order to analyze the energetics of chemical phenomena at electrode-electrolyte interfaces. Expand
Controlling potential difference between electrodes based on self-consistent-charge density functional tight binding.
A self-consistent-charge density functional tight binding based method to model a pair of electrodes in electrochemical cells under the constant-potential condition that can treat systems as large as those studied in classical atomistic simulations and describe the electronic response of electrodes quantum mechanically and more accurately than the classical counterparts.
