Abstract: Abstract The synthesis of connections between two or more different carbon nanotubes is an important step in the development of carbon nanotube-based electronic devices and circuits1,2,3,4. But this is difficult to achieve using conventional methods to grow carbon nanotubes5 because the straight tube structure cannot be controllably altered along its length. Various ideas for post-growth modifications have been suggested6, but these have been hard to implement and are prone to defects. Here we use nano-structured template channels to grow individual Y-junction carbon-nanotube heterostructures by the pyrolysis of acetylene with cobalt catalysis.
