Abstract

Carbon Nanotubes (CNTs) have been attracted much interest on field emission materials due to their unique morphology and excellent properties. Especially, the point typed field emitter can be used for x-ray sources and electron beam sources. Recently, CNT based point emitters are considered as a powerful candidate for high performance x-ray tube or electron beam source applications. Because CNT point x-ray tube can promise high speed response time, a small electron beam spot, long lifetime, a high density x-ray, multifunctional x-ray sources, and a small size system. Here, we demonstrate fabrication methods for several CNT point emitters and also evaluate their field emission properties and field emission stability.
