提出了对电极极化的定量描述，这是一种普遍存在的现象，发生在金属和离子导体之间的界面上，导致样品电池的净介电响应增加许多个数量级。由于库仑相互作用，载流子在金属/离子导体界面的迁移率大大降低，这种方法定量地再现了观察到的标度定律，并开辟了界面电荷输运物理的前景。
A quantitative description is suggested for electrode polarization, an ubiquitous phenomenon which takes place at the interface between a metallic and an ionic conductor and results in an increase by many orders of magnitude in the net dielectric response of the sample cell. Based on the fact that due to coulombic interactions, the mobility of charge carriers is drastically slowed down at the metal/ionic conductor interface, this approach quantitatively reproduces the observed scaling laws and opens perspectives in the physics of charge transport at interfaces.
