Abstract :
Effect of carbon nanotube pillar arrays´ edge effect on field emission characteristics is first studied. The ratio of field emission current density at 5.733V/μm is about 55: 6.5: 1 which is nearly proportional to the edge ratio (50:5:1) for small, middle, and large sizes of CNTs´ arrays. Besides, ultra low turn-on field (~1.4 V/μm), well emission image uniformity and stability of about ±6.52 % at 650V were also achieved.
