WebStern combined the Helmholtz model and the Gouy-Chapman model and divided the EDL into two characteristically distinct layers, i.e., the Stern layer (Helmholtz layer) and the diffuse layer (Gouy-Chapman layer), as shown in Fig. 2.5. The Stern layer takes care of the specific absorption of the ions on the electrode surface while the diffuse ...
