Abstract

Well-aligned carbon nanotubes in specific pattern were synthesized by catalytic thermal chemical vapor deposition technique. The carbon nanotubes were then coated with MgO layer of different thicknesses to improve the field emission property. Stable emission with a low turn-on voltage of about 116 V was observed from the aligned nanotubes coated with a MgO layer of thickness 10 nm. The current fluctuation for 8hr was found to be as low as 20% for MgO (10 nm) coated nanotubes.
