Tailoring on-surface molecular reactions and assembly through hydrogen-modified synthesis: From triarylamine monomer to 2D covalent organic framework
Zachery A. Enderson, Harshavardhan Murali, Raghunath R. Dasari +6
Relative to conventional wet-chemical synthesis techniques, on-surface synthesis of organic networks in ultrahigh vacuum has few control parameters. The molecular deposition rate a…
Grain Boundary Loops in Graphene
Eric Cockayne, Gregory M. Rutter, Nathan P. Guisinger +3
Topological defects can affect the physical properties of graphene in unexpected ways. Harnessing their influence may lead to enhanced control of both material strength and electri…
Epitaxial Graphenes on Silicon Carbide
Phillip N. First, Walt A. de Heer, Thomas Seyller +3
The materials science of graphene grown epitaxially on the hexagonal basal planes of SiC crystals is reviewed. We show that the growth of epitaxial graphene on Si-terminated SiC(00…
Structural Determination of Multilayer Graphene via Atomic Moiré Interferometry
David L. Miller, Kevin D. Kubista, Gregory M. Rutter +4
Rotational misalignment of two stacked honeycomb lattices produces a moiré pattern that is observable in scanning tunneling microscopy as a small modulation of the apparent surface…
The interface structure of epitaxial graphene grown on 4H-SiC(0001)
J. Hass, J. E. Millan-Otoya, P. N. First +1
We present a structural analysis of the graphene-4HSiC(0001) interface using surface x-ray reflectivity. We find that the interface is composed of an extended reconstruction of two…
Hot Dirac Fermions in Epitaxial Graphene
Dong Sun, Zong-Kwei Wu, Charles Divin +5
We investigate the ultrafast relaxation dynamics of hot Dirac fermionic quasiparticles in multilayer epitaxial graphene using ultrafast optical differential transmission spectrosco…
