絶縁液体薄膜の導電特性

Abstract

To understand the current peak phenomena appearing in conduction in dielectric liquid films, it is important to take into account the formation of the diffuse layer at the interface between metal and the liquid. The liguid always contains some free ions that are attracted by a metal. Some of them (usually negative) will experience a stronger attraction, while an equivalent amount of positive ions will stay on the liquid side, and will give rise to electrical unbalance in liquid. It is clearly shown by both experiments and numerical analyses that the unbalance in amount between positive and negative ions is the essential factor to explain the tansient current-voltage characteristics of dielectric liquid films.
