From: Highly stable carbon nanotube field emitters on small metal tips against electrical arcing
Field emission properties and emission stabilities of the fabricated CNT emitters after the electrical conditionings. (a) Field emission properties of the fabricated CNT emitters after the conditioning process. Five J-E measurements were performed. One arcing occurred at the maximum current density of the fourth run (pink arrow). Inset graph and image in (a) are the FN plots of the J-E curves of the CNT emitter and the wettability of metal mixture binders on the copper tip substrate after annealing at 900°C, respectively. (b) Emission stabilities of the fabricated CNT emitters at different electric fields.
