"The rise of white graphene"
Graphene nanoribbons – atomically-thin strips of graphene that are just a few nanometers wide – are considered to be excellent candidates for future electronics applications as their properties can be adjusted through width and edge shape. Along with graphene, boron nitride nanoribbons have attracted more and more fundamental research interest. For instance, researchers have found that magnetism could be induced in such ribbons by the replacement of B or N with Be, B, C, N, O, Al, and Si, or with vacancy defects. They also found that the ribbons could have a narrowed band gap and improved electrical conductivity tuned by a transverse electric field or special edge structure. These findings promise a bright future in in optoelectronics and spintronics for atomically thin boron nitride nanoribbons... In new work that represents an important step in bridging theoretical predictions and experimental realization of atomically thin boron nitride nanoribbons, [Haibo] Zeng and coworkers (from National Institute for Materials Science (NIMS) in Japan and Nanjing University of Aeronautics and Astronautics (NUAA) in China) demonstrate the successful fabrication of 'white graphene' nanoribbons – made of thermally and chemically stable atomic layers of hexagonal boron nitride (h-BN) – by unwrapping multiwalled boron nitride nanotubes under delicate argon plasma etching. The team has reported their findings in the October 28, 2010 online issue of Nano Letters.
