Carbon nanotube growth for field emission display application

Microscopic origin of current degradation of fully-sealed carbon-nanotube field emission display

The current-degradation mechanism of a fully sealed, carbon-nanotube field emission display is investigated experimentally and theoretically. From residual gas analysis, it is strongly evidenced that CH3 radicals from the organic materials in the paste deteriorate emission properties. Based on ab initio methods, it is found that CH3 radicals can increase electrical resistance of the nanotube an...

Carbon-nanotube-polymer nanocomposites for field-emission cathodes.

The electron field-emission (FE) characteristics of functionalized single-walled carbon-nanotube (CNT)-polymer composites produced by solution processing are reported. It is shown that excellent electron emission can be obtained by using as little as 0.7% volume fraction of nanotubes in the composite. Furthermore by tailoring the nanotube concentration and type of polymer, improvements in the c...

Characterizing Multi-Walled Carbon Nanotube Synthesis for Field Emission Applications

Electron field emission from transparent multiwalled carbon nanotube sheets for inverted field emission displays

Strong, conducting, transparent carbon nanotube sheets were prepared by solid-state draw from well-ordered, aligned multiwalled carbon nanotube (MWCNT) forests [Zhang et al., 2005] [1]. Study of electron field emission from such transparent MWCNT sheets shows threshold fields of less than 0.5 V/lm with current densities high enough for display applications. Step-like field emission current incr...
