Grapevine-like growth of single walled carbon nanotubes among vertically aligned multiwalled nanotube arrays
2001
Applied Physics Letters
Preserved Fulltext
Large arrays of self-oriented, multiwalled carbon nanotubes ͑MWNTs͒ have been obtained by chemical vapor deposition. It has so far been impossible to translate this idea for growing single walled nanotubes ͑SWNTs͒ but we show here that oriented growth of SWNTs among vertically aligned MWNT arrays can be realized by the catalytic pyrolysis of ferrocene and xylene. The MWNTs act as the support structures for SWNTs, forcing them to grow upward steadily, like grapevines. The growth of vertically
