We developed a novel process to fabricate point-type carbon nanotube (CNT) emitters formed by transferring a CNT film onto a Ni-coated Cu wire with a diameter of 1.24 mm. A Ni layer plays a role in enhancing the adhesion of CNTs to the substrate and improving their electrical resistance and field emission characteristics. On firing at 400 ˚C, CNTs appear to directly bonded to a Ni layer. With a Ni...
The fabrication and field emission characteristics are reported for point-type carbon nanotube (CNT) emitters formed by transferring a CNT film onto a Ni-coated Cu wire with a diameter of 1.24mm. A Ni layer plays a role in enhancing the adhesion of CNTs to the substrate and improving their field emission characteristics. On firing at 400°C, CNTs appear to directly bonded to a Ni layer. With a Ni layer...
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...
This study analyzed the composition of residual gases inside a vacuum-sealed panel, which was composed of a CNT emitter cathode plate, a phosphor anode, and glass spacers, all kept in vacuum, revealing that CO, CO2, N2, CH4, H2, C2H6, and Ar existed inside the panel. The CNT emitter cathode was prepared in a diode structure by using the CNT paste, producing an array of dots with a diameter of 10 mum...
In this study, the authors fabricated a transparent cathode back plate by depositing an ultra-thin film of single walled CNTs (SWCNTs) on an indium tin oxide (ITO)-coated glass substrate. First, an aqueous CNT solution was prepared by ultrasonic ally dispersing purified SWCNTs in deionized water with sodium dodecyl sulfate (SDS). After centrifugation, several milliliters or even a hundred of microliters...
