    Direct chemical conversion of graphene to boron- and nitrogen- and carbon-containing atomic layers

    Graphene and hexagonal boron nitride are typical conductor and insulator, respectively, while their hybrids hexagonal boron carbonitride are promising as a semiconductor. Here we demonstrate a direct chemical ...
