Nanopatterning of catalyst by Dip Pen nanolithography (DPN) for synthesis of carbon nanotubes (CNT)

Scanning. 2010 Jan-Feb;32(1):42-8. doi: 10.1002/sca.20184.

Abstract

Carbon nanotubes (CNT) were synthesized on nanopatterned catalysts. The catalyst nanoparticles were obtained using dip pen nanolithographytechnique. Dip pen nanolithography technique was used to deposit NiCl(2) nanopatterns with sub-200 nm feature sizes on a silicon substrate. The deposited features were verified by using lateral force microscopy. The substrate was then placed in a plasma-enhanced chemical vapor deposition instrument to synthesize CNT. The synthesized CNT were characterized using scanning electron microscopy and energy dispersive x-ray spectroscopy.
