Characterization of graphene through anisotropy of constant-energy maps in angle-resolved photoemission
M. Mucha-Kruczynski, O. Tsyplyatyev, A. Grishin +4
We show theoretically how constant-energy maps of the angle-resolved photoemission intensity can be used to test wave function symmetry in graphene. For monolayer graphene, we demo…
Morphology of graphene thin film growth on SiC(0001)
Taisuke Ohta, Farid El Gabaly, Aaron Bostwick +6
Epitaxial films of graphene on SiC(0001) are interesting from a basic physics as well as applications-oriented point of view. Here we study the emerging morphology of in-vacuo prep…
Scanning tunneling spectroscopy of inhomogeneous electronic structure in monolayer and bilayer graphene on SiC
Victor W. Brar, Yuanbo Zhang, Yossi Yayon +6
We present a scanning tunneling spectroscopy (STS) study of the local electronic structure of single and bilayer graphene grown epitaxially on a SiC(0001) surface. Low voltage topo…
Symmetry Breaking in Few Layer Graphene Films
Aaron Bostwick, Taisuke Ohta, Jessica L. McChesney +4
Recently, it was demonstrated that the quasiparticle dynamics, the layer-dependent charge and potential, and the c-axis screening coefficient could be extracted from measurements o…
Massive enhancement of electron-phonon coupling in doped graphene by an electronic singularity
Jessica L. McChesney, Aaron Bostwick, Taisuke Ohta +4
The nature of the coupling leading to superconductivity in layered materials such as high-Tc superconductors and graphite intercalation compounds (GICs) is still unresolved. In bot…
