METAL-INSULATOR-METAL SOLID-STATE RECTIFIER

摘要

A metal-insulator-metal layered structure is disclosed which is useful as a rectifier of AC voltage. One of the metal layers is advantageously in the form of a crossgrid-type geometry, in order to afford a large perimeter of contact with the insulator layer. Electrons are injected at the edges of the metal grid through the insulator when the grid goes electrically negative, but not when it goes positive; thereby, rectifying properties are afforded by this metal-insulator-metal structure.
