Unraveling the electronic structure of narrow atomically-precise chiral graphene nanoribbons

Recent advances in graphene nanoribbon-based research have demonstrated the controlled synthesis of chiral graphene nanoribbons (cGNR) with atomic precision using strategies of on-surface chemistry. However their electronic characterization, including typical figures of merit like band gap or fronti...

Description
Summary:Recent advances in graphene nanoribbon-based research have demonstrated the controlled synthesis of chiral graphene nanoribbons (cGNR) with atomic precision using strategies of on-surface chemistry. However their electronic characterization, including typical figures of merit like band gap or frontier bands effective masses, has not yet been reported. In this work, we provide a detailed characterization of (3,1)-cGNRs on Au(111). The structure and epitaxy, as well as the electronic band structure of the ribbons, are analyzed by means of scanning tunneling microscopy and spectroscopy, angle resolved photoemission and density functional theory.
