Electron Emitters

We fabricated carbon nanotube (CNT) cold cathode emitters with enhanced and stable electron emission properties and long-time stability with electrical aging as a post-treatment. Our CNT field emitters showed improved electrical properties by electrical aging. We set the applied bias for effective electrical aging, with the bias voltage defined at the voltage where Joule heating appeared. At the initial stage of aging, the electron emission current started to increase and then was saturated within 3 h. We understood that 5 h aging time was enough at proper aging bias. If the aging bias is higher, excessive heating damages CNT emitters. With the electrical aging, we obtained improved electron emission current from 3 mA to 6 mA. The current of 6 mA was steadily driven for 9 h.

Insulation Performance

Using black insulation slurry as manufacture material, the high emitter-isolating-layer was fabricated on the cathode plate. The high emitter-isolating-layer which possessed good insulation performance was composed of many parallel emitter-isolation-stripes, which the bottom cathode electrode would be exposed in the center of the emitter-isolation-stripe. The carbon nanotube paste was prepared onto the cathode plate to form the field emitters. And the field emission display panel with high emitter-isolating-layer was demonstrated, which the better field emission property including the large emission current and stable electron emission was confirmed.
