Abstract
Large arrays of self-oriented, multiwalled carbon nanotubes (MWNTs) have be en obtained by chemical vapor deposition. It has so far been impossible to translate this idea for growing single walled nanotubes (SWNTs) but we show here that oriented growth of SWNTs among vertically aligned MWNT arrays ca n be realized by the catalytic pyrolysis of ferrocene and xylene. The MWNTs act as the support structures for SWNTs, forcing them to grow upward stead ily, like grapevines. The growth of vertically aligned SWNT over large area s brings about the possibility of exploring their properties in select conf igurations. (C) 2001 American Institute of Physics.
