Research Abstract |
The influence of geometry of a carbon nanotube(CNT) pillar array on its field-emission properties was investigated for the purpose of designing a high-efficiency CNT field-emitter array. Here the dependence of the field-emission(FE) properties(turn-on voltage and emission site distribution) on the pillar pitch and the shape was examined. Our results showed that the change of the pillar shape from a square shape to a"mountain shape", which was fabricated by the self-aligned CNT growth process, improved the FE properties. This improvement is due to the dispersed growth morphology, which reduces the field-screening effect at the top of the mountain-shaped pillars.
