An Amyloid fibril, which is linear protein with a width of less than 10 nm and length of more than 1 m, was used as amorphous carbon template for graphene nanoribbons (GNRs) synthesized by solid-phase graphitization using liquid Ga as catalyst. The crystal quality of GNRs became better with increase of the synthesis temperature. On the other hand, the shape of GNRs synthesized at higher temperature became broader and couldn’t keep the original amyloid shape. The GNRs synthesized at 900 oC seemed to maintain the original amyloid shape in the SEM observation. However, the conducting paths of GNRs synthesized at 900 oC were found to be slightly diffused outside the topography of GNRs in the conductive atomic force microscopy map. In addition, some of the sapphire terrace edges of the substrate showed conductivity, which indicates that growth mechanisms of graphene on a sapphire substrate might be step flow growth mode.
