Abstract:

[PROBLEMS] To provide a flexible capacitor that can be easily prepared at low temperature. [MEANS FOR SOLVING PROBLEMS] There is provided a capacitor comprising two electrodes and, interposed therebetween, a dielectric layer characterized in that the dielectric layer comprises an insulating organic material and, contained therein, metal microparticles and/or an organic material as a charge trap and that the ionization potential and electron affinity of the metal microparticles, etc. are on an energy level between ionization potential and electron affinity of the insulating organic material. Once a charge is introduced in the metal microparticles, etc. by voltage application, the charge is confined within the metal microparticles, etc. due to the energy level relationship with the insulating organic material. The confined charge conducts the same function as that of the induced polarization of dielectric material, so that an effectively very high dielectric constant can be attained even if insulating organic materials of low dielectric constant are employed.
