ABSTRACT:
An electron device employing an electron source including a polycrystalline diamond film having a surface with a plurality of crystallographic planes some of which exhibit a very low
egative electron affinity such as, for example, the 111 crystallographic plane of type II-B diamond. Electron devices employing such electron sources are described including image generation electron devices, light source electron devices, and information signal amplifier electron devices.
