Inducing Metallicity in Graphene Nanoribbons via Zero-Mode Superlattices
Daniel J. Rizzo, Gregory Veber, Jingwei Jiang +7
The design and fabrication of robust metallic states in graphene nanoribbons (GNRs) is a significant challenge since lateral quantum confinement and many-electron interactions tend…
Hierarchical On-Surface Synthesis of Deterministic Graphene Nanoribbon Heterojunctions
Christopher Bronner, Rebecca A. Durr, Daniel J. Rizzo +8
Bottom-up graphene nanoribbon (GNR) heterojunctions are nanoscale strips of graphene whose electronic structure abruptly changes across a covalently bonded interface. Their rationa…
Unoccupied electronic band structure of the semi-metallic Bi(111) surface probed with two-photon photoemission
Christopher Bronner, Petra Tegeder
While many photoemission studies have dealt with both the bulk band structure and various surface states and resonances, the unoccupied electronic structure above the Fermi level o…
Electronic structure of a subnanometer wide bottom-up fabricated graphene nanoribbon: End states, band gap and dispersion
C. Bronner, F. Leyssner, S. Stremlau +4
Angle-resolved two-photon photoemission and high-resolution electron energy loss spectroscopy are employed to derive the electronic structure of a sub-nanometer tomically precise q…
