Abstract
We fabricated the point emitter using a tip-treated carbon nanotube (CNT) fiber. The CNT point emitter showed the high emission current and good emission stability. It is considered that the excellent field emission properties are attributed to a large field enhancement factor caused by a large aspect ratio of the sharp tip of the point emitter and the tight binding of CNTs.
