Precise graphene nanoribbons (GNRs) with periodic regions of
zigzag-edge were produced using a novel bottom-up fabrication method by Prof.
Patrick Han and Prof. Taro Hitosugi, in collaboration with Prof. Naoki Asao,
Prof. Kazuto Akagi, and Prof. Paul S. Weiss at the Advanced Institute for
Materials Research (AIMR), Tohoku University. This fabrication method, which
also controls GNR growth direction and length distribution, maybe a stepping
stone towards future graphene-device fabrication by self-assembly.
