Title: On-surface synthesis and spectroscopic characterization of laterally extended chevron graphene nanoribbons

Journal Article · · ChemPhysChem

In this work, we introduce on-surface synthesis and spectroscopic study of laterally extended chevron graphene nanoribbons (GNRs) and compare them with the established chevron GNRs, emphasizing the consistency of bandgap reduction of semiconducting GNRs with increased width. The extended chevron GNRs grown on Au(111) exhibit a bandgap of about 2.2 eV, which is considerably smaller than the values reported for chevron GNRs in similar studies.
