Disclosed are embodiments of a device and method of forming the device that utilize metal ion migration under controllable conditions. The device embodiments comprise two metal electrodes separated by one or more different dielectric materials. One electrode is sealed from the dielectric material, the other is not. The device is adapted to allow controlled migration of embedded metal ions from the unsealed electrode into dielectric material to form a conductive path under field between the electrodes and, thereby, to decrease the resistance of the dielectric material. Reversing the field causes the metal ions to reverse their migration, to break the conductive metallic path between the electrodes and, thereby, to increase the resistance of the dielectric material. Thus, the device can comprise a simple switch or programmable resistor. Additionally, by monitoring the resistance change, a two-state, two-terminal, silicon technology-compatible, flash memory device with a very simple tuning process can be created.

An electrolytic capacitor that contains an anodically oxidized porous anode, cathode, and an electrolyte that contains an alkali metal salt and ionically conductive polymer is provided. The alkali metal salt forms a complex with the ionically conductive polymer and thereby improves its ionic conductivity, particularly at higher temperatures. The electrolyte also contains an organic solvent that reduces the viscosity of the electrolyte and helps lower the potential barrier to metal ion transport within the electrolyte to improve conductivity.

The liquid nature of the electrolyte enables it to more readily enter the pores of the anode via capillary forces and improve specific capacitance. Further, although a liquid, its viscous nature may inhibit the likelihood of leakage.
