|Title:||Tantalum based coated substrates for controlling the diameter of carbon nanotubes|
|Abstract:||The diameter of carbon nanotubes deposited on TaN coated silicon substrates by catalytic chemical vapor deposition strongly depends on the N/Ta ratio in the coating. The coating characteristics are tailored by controlling the deposition parameters in a plasma reactive sputtering process. Photoelectron emission spectroscopy and X-ray diffraction of the coatings show the formation of a composite material. The presence of multi-wall nanotubes is confirmed by transmission electron microscopy. The results show that the structure of the TAN coating modifies the catalyst (Fe) effect changing the kinetics of the nanotube growth. (c) 2009 Elsevier Ltd. All rights reserved.|
