Topic: Graphene Nanoribbons – Merging the Worlds of Graphenes and Conjugated Polymers
Abstract Carbon nanostructures, a hot topic of modern material science, are not only a playground for physics and engineering, but also a challenge for chemical synthesis. Especially exciting additions to the rich carbon family are graphenes and graphene nanoribbons (GNRs), their geometrical cutouts. Graphenes hold enormous promise, for example, in energy technologies and non-linear optics. However, before they can be employed in electronics and their high charge-carrier mobility be utilized in field-effect transistors (FETs), an opening of their electronic band gaps must be achieved. The best answer to this longstanding problem are GNRs, and this brings precision polymer synthesis into play. While protocols from lithography or unzipping of carbon nanotubes offer no control over length, width and edge structure, bottom-up synthesis is the method of choice.
Utilizing new protocols of polycyclic aromatic hydrocarbon chemistry, we present unprecedented syntheses proceeding in, both, solution and on-surface. The latter approach, which can be scaled up by extension from UHV-conditions to chemical vapor deposition, also allows in-situ monitoring and proof of GNRformation by scanning tunneling microscopy.
Based on these material breakthroughs, we fabricate FETs from single GNRs and GNR-networks and compare the performance with that of conventional conjugated polymers. Surprisingly, the design of GNRs with appropriate combinations of arm-chair and zig-zag edges furnishes robust topological insulators in 2D as well as spin states with high correlation times. There is hope that these features provide entries into spintronics and even quantum computing.
