Angular and local spectroscopic analysis to probe the vertical alignment of N-doped well-separated carbon nanotubes
Article Abstract:
The vertical alignment of well-separated as-grown multiwalled carbon nanotubes (MWCNTs) synthesized by plasma-enhanced chemical vapor deposition (PECVD) is characterized by using the angular analysis of near-edge X-ray absorption fine structure (NEXAFS). The direct comparison of local high-resolution electron energy loss spectroscopy (HREELS) and global NEXAFS characterization methods is very effective for nanomaterials analysis.

Direct evidence for root growth of vertically aligned single-walled carbon nanotubes by microwave plasma chemical vapor deposition
Article Abstract:
The root growth mode of extremely dense and vertically aligned single-walled carbon nanotubes (SWNTs) synthesized by microwave plasma chemical vapor deposition was clarified by a new method, marker growth, which does not require transmission electron microscopy. SWNT layers were grown intermittently on a substrate, and a line between the layers was used as a marker to identify the growth mode.

Vertically aligned dense carbon nanotube growth with diameter control by block copolymer micelle catalyst templates
Article Abstract:
A dense array of vertically aligned carbon nanotubes (CNTs) with a controlled distribution of diameters are grown using block copolymer micelles to form and pattern catalyst particles is presented. Transmission electron microscopy revealed that the CNTs typically had double and triple graphitic layers with normally distributed diameters of (4.5(plusmn)1.1) nm.
