Reversible Coloring and Decoloring Solid-State Device, a Reversible Conductive Property Changing Solid-State Device, a Reversible Refractive Index Changing Solid-State Device, a Nonradiative Display Device, a Conducting Path Device and a Light Waveguide Device

摘要

A reversible coloring and deccoloring solid-state device includes a solid-state electrolyte film and a coloring and decoloring film which colors or decolors the coloring and decoloring film reversibly by applying an electric field. A barrier thin film is inserted between the solid-state electrolyte film and the coloring and decoloring film. The barrier thin film comprises at least one layer which is formed by a material having a band gap energy, functions as a barrier for the carrier movement, and has a thickness of 7 nm to 7±2 nm which does not prevent ion conduction. The coloring and decoloring speed is 0.1 seconds to 0.3 seconds by a voltage driving.
