Title:
Symmetric field emission devices using distributed capacitive ballasting with multiple emitters to obtain large emitted currents at high frequencies
Abstract:
Field emission devices utilizing capacitive ballasting are described with possible uses in industry. The preferred device utilizes opposing electrodes, each with a dielectric layer and a plurality of conductive islands which serve to exchange electrons, generating an oscillatory current. Ideally these islands are dome-shaped and made of a refractory metal such as tungsten of molybdenum. Through proper use and selection of materials, electrical fields with densities of 1014 A/m2 are capable of being generated.
