Electronic characterization of solution-synthesized graphene nanoribbons using scanning tunneling microscopy

This thesis reviews the methods of using bottom-up synthesis to fabricate atomically precise graphene nanoribbons (GNRs). Previous works of on-surface heterojunction GNRs and the dry contact transfer method for solution-synthesized GNRs are presented to show the current status of GNR fabrication. The electronic characterizations of the chevron GNR and new chevron/7A heterojunction GNR with functionalized side chains are also presented using scanning tunneling spectroscopy in a room temperature scanning tunneling microscope. The initial findings of the chevron/7A GNR with functionalized side chains are presented as the building blocks towards combining DNA origami and GNR precursors. Finally, a method is proposed to fabricate organized GNRs by attaching GNR precursors to ssDNA to make DNA origami.
