Abstract

We demonstrated high field emission performance of carbon nanotube paste emitters, which were fabricated by using graphite filler, instead of commonly used metal or SiO₂, or SiC particle fillers. The emitter with an emission area of 0.7 mm in diameter shows a highest current of 8.4 mA before electrical arcing events, corresponding to a current density of 2.2 A/cm². The emitter shows a stable current of 1 mA for 20 h. It is suggested that the paste emitter could be a good candidate for x-ray source applications.
