フレキシブルデバイスのための価数変化可能な極板を持つ蓄電素子の静電気学的考察

Abstract

Charge storage devices in the film-base flexible electronics are very important for the application of those devices in daily life. In order to examine the recently reported solid state capacitor with ionizable charge traps, we present an analysis of an electrostatic model. It shows a charge-voltage characteristic resembling a chemical battery. While the energy density per charge is great in these devices, the energy density of the capacitor with ionizable traps will be lower than that of an ordinary capacitor with metal electrodes, assuming the same withstanding voltage and the same geometry.
