Abstract

Abstract Bamboo-like carbon nanotubes were formed by laser ablation using a graphite target containing 10 weight percentage of NiCo bi-catalyst. The Scanning Electron Microscopy images showed the diameter of the web-like carbon nanotubes formed by graphite-NiCo ranges from 35nm-100nm. The Transmission Electron Microscopy images showed a bamboo-like carbon nanotubes(CNTs) with the diameter in the range of 20-50nm were formed. The bamboo-like carbon nanotubes formed from the experiment showed a defect structures which we attributed it to pulse to pulse width (140 ns) of the 532 nm wavelength laser and the role of the bi-catalyst role during the 5 minute ablation time. Keywords: Carbon Nanotubes, Pulsed laser ablation deposition technique and Bamboo-like.
