Abstract
Copper-filled carbon nanotubes and methods of synthesizing the same are provided. Plasma-enhanced chemical vapor deposition can be used to synthesize vertically aligned carbon nanotubes filled with copper nanowires. The copper filling can occur concurrently with the carbon nanotube growth, and the carbon nanotubes can be completely filled by copper. The filling of Cu inside the CNTs can be controlled by tuning the synthesis temperature.
