Covalent chemistry in graphene electronics

摘要: The atomically flat surface of graphene provides an opportunity to apply carbon–carbon bond-forming chemical reactions engineer the electronic properties circuitry. In particular, covalent functionalization or edge ribbons a novel way introduce patterning that can modulate energy band gap, affect electron scattering, and direct current flow by producing dielectric regions in wafer. We discuss use Raman spectroscopy scanning tunneling microscopy characterize periodicities densities have been produced derivatization epitaxial together with concomitant changes magnetic layer.
