  • Abstract
    We demonstrated a novel point-typed carbon nanotube field emitters using a triangular-shaped carbon nanotube films. We also investigated the field emission properties of the field emitters according to the tip angles. The wider field emitters exhibited higher emission current, and the field emitters with a tip angle of 120° showed extremely high emission current density over 104 A/cm2 (> 10 mA) at a low electric field of 1.24 V/μm.
