Abstract

Pearl-necklace-structured CNT/Co nanocomposite powders, with spherical Co nanoparticles threaded by penetrating CNTs, have been fabricated using a molecular process. The nanocomposite powders have been screen-printed and sintered into CNT-implanted Co nanocomposite emitters, with the CNTs standing upright on the surface of the substrate. The CNT-implanted Co nanocomposite emitters show outstanding field-emission behavior, including a low turn-on electric field and high current density.
