Abstract

In this report, the pillar-shaped carbon nanotubes (CNTs) have been achieved by utilizing an Fe-Ti codeposited layer as catalyst in thermal chemical vapor deposition system (T-CVD). By adjusting the ratio of distance between neighboring pillars (R) to the pillar height (H) as 2.5, the field emission characteristics can be effectively improved by reducing the screening effect. The turn-on field was remarkably decreased to 0.95 V/um with a very high current of 4.98mA for a device with area of 0.02cm2. The coefficient of variation (CV) of the emission current was as low as 20.59 % at 800V for 3600sec.
