Zusammenfassung: | Electrochemical double-layer emersion is a powerful tool for probing molecular and electronic structural properties of the electrode-electrolyte interfacial region. It also poses some interesting questions as to the potential distribution in the emersed layer and to potential monitoring outside the emersed layer.
In this work we analyse double-layer emersion when a finite-size electrode is emersed at constant potential and the outer potential vanishes at infinite distance from the electrode. This corresponds to a finite residual surface charge and differs from a previous model in which no external electric field remained outside the emersion layer. Emersion is accompanied by a small electrode discharge which can be investigated experimentally and reflects the dielectric and spatial properties of the emersed layer. |
