Researchers from Göttingen and Pasadena (USA) have produced an “atomic scale movie” showing how hydrogen atoms chemically bind to graphene in one of the fastest reactions ever studied.
Graphene is celebrated as an extraordinary material. It consists of pure carbon, only a single atomic layer thick. Nevertheless, it is extremely stable, strong, and even conductive. For electronics, however, graphene still has crucial disadvantages. It cannot be used as a semiconductor, since it has no bandgap. By sticking hydrogen atoms to graphene such a bandgap can be formed. Now researchers from Göttingen and Pasadena (USA) have produced an…
