“…Field emission displays fabricated by screenprinting CNT pastes [4][5][6] have been widely used due to their large area. However, the purification processes of CNTs prepared for the screen-printing method by arc-discharge or laser-ablation are usually time consuming and complicated [7][8][9].…”

The uniform body emission properties of lateral single-walled carbon nanotubes (SWNTs) emitters grown by chemical vapor deposition are reported. Lateral SWNTs lying on the substrate were found to possess a turn-on field of at least 1.67 V/µm and a field enhancement factor of 5223 at most. A flat panel display requiring 1 mA/cm 2 was carried out at 4.7 V/µm. The large area uniform luminescence was obtained due to the uniform electrical field intensities throughout the body of SWNTs according to a calculation of electrical field distribution. Good field emission characteristics with a simple process could be more applicable for display applications.

“…One is directly growing CNTs on the substrate and the other is transferring CNT powder to the substrate through coating, spraying, printing, or electrophoresis. 2,3 In order to find a simple method to make a planar emitter in a large area, we have developed a procedure involving a printing technique, hydrogen plasma process ͑HPP͒, and some other processes. The field emitters made with this procedure significantly improved their field emission properties.…”

A configuration of carbon nanotubes (CNTs) whose surfaces were fully covered with nanoscale nodes was developed in our laboratory. We named this material nodular CNTs or NCNTs. A hydrogen plasma process was used to turn common CNTs into NCNTs. Combined with this process, a technique has been developed to make planar NCNTs field emitters. Field emission experiments showed that planar NCNTs emitters had superior field emission characteristics. Specifically, the emission site density was increased by the order of 106/cm2. A suggestion was given to interpret the formation of NCNTs and a simple model was also proposed to explain the improvement of field emission properties. This technique was found to be an easy way to change the geometric character of CNTs in large quantities and will be useful for creating planar field emitters used in field emitter light sources or display devices.

“…6,7 To overcome this problem, much efforts have been focused to develop a low temperature process for CNTs deposition and patterning technology. [8][9][10][11] Currently, fully sealed prototype FEDs with CNT emitters have been demonstrated using a screen-printing process. 8,9 For micrometer-sized patterning, however, the screen-printing process has some limitations in obtaining fine-pitched patterns because of fluid-containing paste properties.…”
