WEBWhere S = hs is the eective stern layer thickness, taking into account. the variation in dielectric constant, and c0. = / D is the Debye-H ̈uckel capacitance of the diuse layer, which is equivalent to the Gouy-Chapman capacitance for low potentials.
Gouy-Chapman Theory - an overview | ScienceDirect Topics
WEBStern modified the Gouy-Chapman model by introducing a layer of thickness, δ s, known as the Stern Layer, in which there is no charge and which separates the counterion charge from the charge of the particle surface [150, Chapter 5].

WEBMar 22, 2021 · In this case, the Stern layer mainly consists of polarized water molecules with the dielectric constant in response to the local electric field approximately following the rescaled Kirkwood equation.
Differential capacitance of the electric double layer: mean-field ...
WEBFeb 1, 2019 · A long-established method to improve the predictions of mean-field models is to introduce a Stern layer. It is reasonable to assume that some of the mobile counterions of an EDL adsorb onto the electrode, thereby creating a region that separates the charged surface from the diffuse part of the EDL.
WEBChapman-Stern (GCS) model [17] underlies most of the current capacitance models, where the electrolytic part of the electrochemical double-layer is split into two regions: Fist, the inner Stern layer, which is bounded by the plane of closest approach of solvated ions (outer Helmholtz plane) giving rise to the Helmholtz capacitance C H ...
Gouy-Chapman Theory | SpringerLink
WEBJan 1, 2018 · Definition. Gouy-Chapman theory (Gouy 1910; Chapman 1913) is an electrostatic model of the spatial distribution of ions adsorbed, but not immobilized, by a charged particle surface reacting with an aqueous electrolyte solution.
