Efficient Field Emission from Highly Aligned, Graphitic Nanotubes Embedded with Gold Nanoparticles

Abstract

By utilizing highly aligned graphitic nanotubes embedded with gold nanoparticles an efficient field‐emission device can be constructed. These have been synthesized by first preparing composite nanotubes consisting of poly( p ‐phenylenevinylene) and Au nanoparticles by chemical vapor deposition polymerization, followed by carbonization. The Figure shows transmission electron microscopy images of these nanotubes.
