| Research Abstract |
Single- and double- ayer graphene nanoribbons (GNRs) with widths of around 10 nm 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, conductance and carrier mobility were all improved by increasing the temperature of synthesis. The carrier mobility of GNRs synthesized at 1050 degree C was 0.83 cm2/Vs, 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.
