Semiconducting graphene plays an important part in graphene nanoelectronics because of the lack of an intrinsic bandgap in graphene1. Previously two decades, attempts to modify the bandgap either by quantum confinement or by chemical functionalization failed to produce practical semiconducting graphene. Here we demonstrate that semiconducting epigraphene (SEG) on single-crystal https://waferboats35825.blogofoto.com/60162446/not-known-factual-statements-about-silicon-carbide-scrap-value
