Abstract
An emitter includes an electron supply layer, a dielectric layer on the electron supply layer defining an emission area, and a filled zeolite emission layer within the defined emission area and in contact with the electron supply layer. The filled zeolite emission layer holds a semiconductor material within the cage of the zeolite.
