Semiconducting graphene plays an important part in graphene nanoelectronics because of the lack of the intrinsic bandgap in graphene1. Before two decades, attempts to switch the bandgap either by quantum confinement or by chemical functionalization did not produce viable semiconducting graphene. Here we demonstrate that semiconducting epigraphene (SEG) on single-crystal https://silicon-carbide-desulfuri05814.jiliblog.com/86331131/the-basic-principles-of-edge-pro-silicon-carbide
