Abstract

High quality DWNTs (double-walled carbon nanotubes) was produced by a catalytic CVD. The field emission was measured using parallel-plate geometry with a gap distance of 270 - 370 um under a 2 × 10-7 Torr. The turn-on electric field of DWNTs was about 1.7 - 3.5V/um at ∼ 1.0 × 10-7mA/cm2 and the current density of DWNTs was about ∼ 20mA/cm2 at the applied electric field of ∼ 8V/um. The lifetime indicated good stability for 20 hours when constant DC voltage applied at high current density of ∼ 1.0 × 10-3A/cm2.
