Synthesis of Gallium Nitride Nanorods Through a Carbon Nanotube-Confined Reaction

TLDR

The study proposes that carbon nanotubes act as templates confining the reaction to produce gallium nitride nanorods with diameters matching the nanotubes. Gallium nitride nanorods were synthesized by reacting Ga₂O vapor with NH₃ gas in the presence of carbon nanotubes, using the nanotubes as a confined template to produce wurtzite nanorods. The resulting nanorods are 4–50 nm in diameter, up to 25 µm long, and the method may enable synthesis of other nitride nanorods.

Abstract

Gallium nitride nanorods were prepared through a carbon nanotube–confined reaction. Ga 2 O vapor was reacted with NH 3 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.
