Outline of Final Research Achievements

Wide graphene nanoribbons (GNRs) were fabricated via two-zone chemical vapor deposition using 4,4′′-dibromo-p-terphenyl as the precursor. Densely packed arrays of poly(p-phenylene) produced on Au(111) using this method could be converted into wide GNRs via interchain fusion by thermal annealing. The field-effect transistor prepared from these GNRs exhibited an excellent on/off current ratio.
