Abstract

Growth mechanisms of carbon nanotubes are investigated and compared for both high- and lowtemperature synthesis methods through experiments utilizing time-resolved, in situ imaging and spectros-copy. 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 nano-tube arrays (VANTAs) by CVD at 550-900°C.
