Research published in Nature Nanotechnology shows that diamond and graphite are just a few chemical reactions apart. A research team led by Rodney S. Ruoff of Ulsan National Institute of Science and Technology in South Korea has demonstrated conversion of large-area bilayer graphene to F-diamane—an ultrathin, fluorinated diamond-like material—under non-extreme temperature and pressure conditions upon fluorination.
“The conversion from bilayer AB-stacked graphene to the thinnest possible diamond-like material is indeed possible without using extreme conditions, like high pressure,” says Pavel Bakharev, a research fellow in physics at the Center for Multidimensional Carbon Materials (CMCM) at the Institute for Basic Science in Ulsan, South Korea, and lead author of the findings. “[There have been] multiple theoretical papers on this conversion, but until now, it [has never been shown] experimentally.”
