Abstract

We developed a simple process to fabricate point-type CNT emitters by repeatedly coating CNT films with controlled nanotube morphologies and strong adhesion. The CNT emitters produced significantly large field emission current densities at very low electric fields and excellent long-term stability for high current emission. The fabrication processes and characteristics of the CNT electron sources for high-resolution miniaturized X-ray tubes will be presented in detail.
