Atomically-controlled doping site of boron in graphene nanoribbons

In the framework of JST-PRESTO research project, JST-PRESTO, scientists Shigeki Kawai at the Department of Physics at the University of Basel, Shohei Saito at the Research Center for Materials Science at Nagoya University, and Shigehiro Yamaguchi at Institute of Transformative Bio-Molecules at Nagoya University et al., have succeeded in synthesizing boron-doped graphene nanoribbon on a gold surface by on-surface chemical reaction. The chemical structure and electronic properties were characterized by high-resolution atomic force microscopy and scanning tunneling microscopy. The presented investigations are not only of interest for the field of physics, but also for chemistry and engineering since the boron site can tune the band gap and also has a function as a nitric oxide acceptor.
