摘要

本文报道了几种电解质中金电极的双电层的测量结果。在实验中，德拜层沿电极传输一个阻尼电压波，我们用它来探测电极-电解质界面。我们将测量结果与传统的阻抗模型进行了比较，传统的阻抗模型将德拜层原理化为电容。我们不仅对很稀的电解质，而且对离子液体也发现了很好的一致性。然而，同样的模型不适用于浓电解质，因为离子-溶剂-离子相互作用变得重要。

The Debye Layer as a Transmission Line in the 4 Hz-100 kHz Frequency Range.

We report measurements on the electrical double layer at a gold electrode in several electrolytes. In the experiments, the Debye layer transmits a damped voltage wave along the electrode, which we use to probe the electrode-electrolyte interface. We compare the measurements with traditional impedance models, which schematize the Debye layer as a capacitance. We find good agreement not only for very dilute electrolytes but also for an ionic liquid. However, the same model fails for the concentrated electrolyte, as ion-solvent-ion interactions become important.

期刊介绍： An essential criterion for acceptance of research articles in the journal is that they provide new physical insight. Please refer to the New Physical Insights virtual issue on what constitutes new physical insight. Manuscripts that are essentially reporting data or applications of data are, in general, not suitable for publication in JPC B.
