▎ 摘　　要

Graphene nanoribbons (GNRs) were grown on n-type vicinal 6H-SiC substrates as a template, consisting of periodic nanosurface, by chemical vapor deposition (CVD). Selective growth was achieved and resulted in narrow (5-10 nm width) and millimeter-long GNRs. The GNRs contained randomly rotated domains, however, initial nuclei indicated single domain features, possibly aligned to step edges. The resistivity measurement on GNRs grown on semi-insulating SiC substrate indicated transport properties only along GNRs but no current flow across GNRs, indicating growth of electrically isolated bunches of GNRs.
