Hot carbon nanoparticles self-assembled in short pulsed-arc discharge

ABSTRACT: Little is known about the behavior of carbon nanoparticles produced by arc-discharge in which they are so hot that atoms are mobile. We have developed a pulsearc-discharge system to study such nanoparticles, and have recently found that hot carbon nanoparticles of 5-10 nm in diameter were self-assembled into a tree-like structure. Individual nanoproducts within the tree-like structure were deposited uniformly as a monolayer over a macroscopic area of the cathode. The origin of the interaction between nanoparticles and that of deposition parameters are discussed.
