Theoretical solution of the transient current equation for mobile ions in a dielectric film under the influence of a constant electric field

In this paper we consider the one‐dimensional system of a dielectric slab with one type of mobile ions in it, placed between two blocking electrodes. We present an analytical solution for the transient ionic displacement current, neglecting space‐charge effects only. The theoretical results show good agreement with experimental results on Na+, Li+, and K+ ion transport in the oxide of metal‐SiO2‐Si structures.
