Novel nanostructured metallic nanorod arrays with multibranched root tails

摘要

Here we develop a simple electrochemical method to fabricate novel multibranched root-tailed nanorod arrays by a novel electrochemical technique. A formation mechanism of the thick barrier layer and the root-tailed nanorod is proposed. Using this template-assisted method, three-dimensional nanorod arrays were prepared in a controlled manner, which helped to clarify the growth processes close to the bottom of the nanopores. The nanobranched wire, distinct from previous one-dimensional nanowires, should have potential applications in three-dimensional nanoelectronics and nanophotonics.
