Drude Conductivity of Dirac Fermions in Graphene
Jason Horng, Chi-Fan Chen, Baisong Geng +9
Electrons moving in graphene behave as massless Dirac fermions, and they exhibit fascinating low-frequency electrical transport phenomena. Their dynamic response, however, is littl…
Gate-Controlled Ionization and Screening of Cobalt Adatoms on a Graphene Surface
Victor W. Brar, Regis Decker, Hans-Michael Solowan +9
We describe scanning tunneling spectroscopy (STS) measurements performed on individual cobalt (Co) atoms deposited onto backgated graphene devices. We find that Co adatoms on graph…
Instability of two dimensional graphene: Breaking sp2 bonds with soft X-rays
S. Y. Zhou, C. O. Girit, A. Scholl +7
We study the stability of various kinds of graphene samples under soft X-ray irradiation. Our results show that in single layer exfoliated graphene (a closer analogue to two dimens…
A Tunable Phonon-Exciton Fano System in Bilayer Graphene
Tsung-Ta Tang, Yuanbo Zhang, Cheol-Hwan Park +9
Interference between different possible paths lies at the heart of quantum physics. Such interference between coupled discrete and continuum states of a system can profoundly chang…
Tunable Superconducting Phase Transition in Metal-Decorated Graphene Sheets
B. M. Kessler, C. O. Girit, A. Zettl +1
Using typical experimental techniques it is difficult to separate the effects of carrier density and disorder on the superconducting transition in two dimensions. Using a simple fa…
Origin of Spatial Charge Inhomogeneity in Graphene
Yuanbo Zhang, Victor W. Brar, Caglar Girit +2
In an ideal graphene sheet charge carriers behave as two-dimensional (2D) Dirac fermions governed by the quantum mechanics of massless relativistic particles. This has been confirm…
