Topological band gap in intercalated epitaxial graphene
Minsung Kim, Cai-Zhuang Wang, Michael C. Tringides +2
Functional manipulation of graphene is an important topic in view of both fundamental researches and practical applications. In this study, we show that intercalation of 5 trans…
Intercalated Rare-Earth Metals under Graphene on SiC
Nathaniel A. Anderson, Myron Hupalo, David Keavney +2
Intercalation of rare earth metals ( = Eu, Dy, and Gd) is achieved by depositing the metal on graphene that is grown on silicon-carbide (SiC) and by subsequent annealing a…
Intercalated europium metal in epitaxial graphene on SiC
Nathaniel A. Anderson, Myron Hupalo, David Keavney +2
X-ray magnetic circular dichroism (XMCD) reveal the magnetic properties of intercalated europium metal under graphene on SiC(0001). Intercalation of Eu nano-clusters (average size…
The effects of Moire lattice on the electronic properties of graphene
Lunan Huang, Yun Wu, M. T. Hershberger +5
We study structural and electronic properties of graphene grown on SiC substrate using scanning tunneling microscope (STM), spot-profile-analysis low energy electron diffraction (S…
Magnetic properties of Dy nano-islands on graphene
Nathaniel A. Anderson, Qiang Zhang, Myron Hupalo +4
We have determined the magnetic properties of epitaxially grown Dy islands on graphene/SiC(0001) that are passivated by a gold film (deposited in the ultra-high vacuum growth chamb…
Magnetite nano-islands on silicon-carbide with graphene
Nathaniel A. Anderson, Qiang Zhang, Myron Hupalo +3
X-ray magnetic circular dichroism (XMCD) measurements of iron nano-islands grown on graphene and covered with a Au film for passivation reveal that the oxidation through defects in…
Femtosecond Population Inversion and Stimulated Emission of Dense Dirac Fermions in Graphene
T. Li, L. Luo, M. Hupalo +4
We show that strongly photoexcited graphene monolayers with 35fs pulses quasi-instantaneously build up a broadband, inverted Dirac fermion population. Optical gain emerges and dire…
Growth mechanism for epitaxial graphene on vicinal 6H-SiC(0001) surfaces
M. Hupalo, E. Conrad, M. C. Tringides
The inability to grow large well ordered graphene with a specific number of layers on SiC(0001) is well known. The growth involves several competing processes (Si desorption, carbo…
