Abstract
Field emission of carbon nanotubes (CNTs) fabricated by disproportionation of CO has been studied. CNTs fabricated on well-ordered Co nanowire arrays formed on the porous anodic aluminum oxide templates were well graphitized, uniform in diameter and aligned vertically with respect to the plane of the template, and showed a good field emission property. Very uniform emissions were observed from the CNTs fabricated at relatively low temperature, <TEX>$500-600^{\circ}C$</TEX>. Low fabrication temperature such as <TEX>$500^{\circ}C$</TEX> could make it possible to fabricate CNTs on soda lime glass, a low-cost substrate, for display panel.
