Abstract :
The electric field and electron focusing performance of ZnO nano-cone arrays in planar gated emitter is mimulated by finite element method. The influences of the ZnO arrays with various geometric structures on surface field of the cone will be presented. Focusing performance of the electron beam is also discussed.
