Professor Emeritus Rikizo Hatakeyama and Assistant Professor Toshiaki Kato of the Graduate School of Engineering, Tohoku University have developed a novel production and integration method for graphene nanoribbons, which have an one dimensional ribbon-like structure with mono-layer graphene sheet.

This is the first result realized the perfect site- and alignment-controlled growth of graphene nanoribbon on the device substrate. Graphene nanoribbons produced by this method show the very high semiconductor device performances (on/off ratio > 10,000).

These results have been published on September 9, 2012 (GMT) in the Nature Nanotechnology (online edition). The paper's title is "Site- and alignment-controlled growth of graphene nanoribbons from nickel nanobars."
