  • Coupling Epitaxy, Chemical Bonding, and Work Function at the Local Scale in Transition Metal-Supported Graphene 

    Wang, Bo; Caffio, Marco; Bromley, Catherine; Fruchtl, Herbert Anton; Schaub, Renald (2010-10) - Journal article
    Resonance tunneling spectroscopy and density functional theory calculations are employed to explore local variations in the electronic surface potential of a single graphene layer grown on Rh(111). A work function modulation ...
  • Ethene to graphene : surface catalyzed chemical pathways, intermediates, and assembly 

    Wang, Bo; König, Michael; Bromley, Catherine; Yoon, Bokwon; Treanor, Michael-John; Garrido Torres, José A.; Caffio, Marco; Grillo, Federico; Fruchtl, Herbert; Richardson, Neville V.; Esch, Friedrich; Heiz, Ueli; Landman, Uzi; Schaub, Renald (2017-05-04) - Journal article
    Diverse technologies, from catalyst coking to graphene synthesis, entail hydrocarbon dehydrogenation and condensation reactions on metals, and assembly into carbon overlayers. Imperative to gaining control over these ...
  • New class of metal bound molecular switches involving H-tautomerism 

    Simpson, Grant James; Hogan, Simon William Leslie; Caffio, Marco; Adams, Christopher J.; Fruchtl, Herbert Anton; van Mourik, Tanja; Schaub, Renald (2014-01-28) - Journal article
    A potential end-point in the miniaturization of electronic devices lies in the field of molecular electronics, where molecules perform the function of single components. To date, hydrogen tautomerism in unimolecular switches ...
  • Size-Selective Carbon Nanoclusters as Precursors to the Growth of Epitaxial Graphene 

    Wang, Bo; Ma, Xiufang; Caffio, Marco; Schaub, Renald; Li, Wei-Xue (2011-02-09) - Journal article
    The nucleation and growth mechanisms of graphene on Rh(111) via temperature-programmed growth of C2H4 are studied by scanning tunneling microscopy and spectroscopy, and by density functional theory calculations. By combining ...
