Abstract
Field emission of high current from carbon nanotube (CNT) emitters usually enforces them to be exposed to high electric fields (electrostatic forces) and Joule heating. In addition, vacuum packaging of field emitter devices are often carried out at high temperature. Under such circumstances, CNT emitters may be easily damaged, thus requiring highly crystalline and thermally stable CNTs. This study synthesized CNTs having high crystallinity by arc discharge and prepared the CNT paste using them. Compared to CNTs grown by catalytic chemical vapor deposition, the arc-produced CNTs showed higher thermal stability and better lifetime performance.
