Gallium nitride nanorods were prepared through a carbon
nanotube-confined reaction. Ga2O vapor was reacted
with NH3 gas in the presence of carbon nanotubes to form
wurtzite gallium nitride nanorods. The nanorods have a diameter of 4 to
50 nanometers and a length of up to 25 micrometers. It is proposed that
the carbon nanotube acts as a template to confine the reaction, which
results in the gallium nitride nanorods having a diameter similar to
that of the original nanotubes. The results suggest that it might be possible to synthesize other nitride nanorods through similar carbon
nanotube-confined reactions.
