Single- and double-layer graphene nanoribbons (GNRs) with widths of around 10nm were synthesized
directly onto an insulating substrate by solid-phase graphitization using a gallium vapor catalyst and
carbon templates made of amyloid fibrils. Subsequent investigation revealed that the crystallinity,
conductivity, and carrier mobility were all improved by increasing the temperature of synthesis. The
carrier mobility of the GNR synthesized at 1050 C was 0.83 cm2 /V s, which is lower than that of
mechanically exfoliated graphene. This is considered to be most likely due to electron scattering by the
defects and edges of the GNRs.
