Abstract
AbstractGrowth mechanisms of carbon nanotubes are investigated and compared for both high‐ and low‐temperature synthesis methods through experiments utilizing time‐resolved, in situ imaging and spectroscopy. High‐speed videography and pyrometry measured the timeframes for growth for single‐wall carbon nanotubes (SWNTs) and nanohorns (SWNHs) by laser vaporization (LV) at 1150 °C, revealing that C can self‐assemble at high temperatures preferentially into SWNH structures without catalyst assistance at rates comparable to catalyst‐assisted SWNT growth by either laser vaporization or chemical vapor deposition (CVD). Laser interferometry and videography reveal the coordinated growth of vertically‐aligned nanotube arrays (VANTAs) by CVD at 550–900 °C. (© 2007 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
