High brightness boron-containing electron beam emitters for use in a vacuum environment

High brightness boron-containing electron beam emitters for use in a vacuum environment

An emitter containing a metal boride material has an at least partly rounded tip with a radius of 1 μm or less. An electric field can be applied to the emitter and an electron beam is generated from the emitter. To form the emitter, material is removed from a single crystal rod to form an emitter co...

description An emitter containing a metal boride material has an at least partly rounded tip with a radius of 1 μm or less. An electric field can be applied to the emitter and an electron beam is generated from the emitter. To form the emitter, material is removed from a single crystal rod to form an emitter containing a metal boride material having a rounded tip with a radius of 1 μm or less.
