Abstract

See full text

Improved field emission cathodes comprise a fiber of highly aligned and densely packed single-wall carbon nanotubes, double-wall carbon nanotubes, multi-wall carbon nanotubes, grapheme nanoribbons, carbon nanofibers, and/or carbon planar nanostructures. The fiber cathodes provide superior current carrying capacity without degradation or adverse effects under high field strength testing. The fibers also can be configured as multi-fiber field emission cathodes, and the use of low work function coatings and different tip configurations further improves their performance.
