合成两个或多个不同碳纳米管之间的连接是发展基于碳纳米管的电子器件和电路的重要一步。但使用传统方法生长碳纳米管很难实现这一点，因为直管结构不能沿其长度可控地改变。关于生长后修改的各种想法已经被提出，但这些想法很难实施，而且容易出现缺陷。在这里，我们使用纳米结构的模板通道，通过乙炔在钴催化下的裂解来生长单独的Y结碳纳米管异质结构。
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 circuits,,,. But this is difficult to achieve using conventional methods to grow carbon nanotubes because the straight tube structure cannot be controllably altered along its length. Various ideas for post-growth modifications have been suggested, 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.
