Raman Spectroscopy of magneto-phonon resonances in Graphene and Graphite
Sarah Goler, Jun Yan, Vittorio Pellegrini +1
The magneto-phonon resonance or MPR occurs in semiconductor materials when the energy spacing between Landau levels is continuously tuned to cross the energy of an optical phonon m…
Graphene growth on h-BN by Molecular Beam Epitaxy
Jorge M. Garcia, Ulrich Wurstbauer, Antonio Levy +10
The growth of single layer graphene nanometer size domains by solid carbon source molecular beam epitaxy on hexagonal boron nitride (h-BN) flakes is demonstrated. Formation of sing…
Molecular beam growth of graphene nanocrystals on dielectric substrates
Ulrich Wurstbauer, Theanne Schiros, Cherno Jaye +9
We demonstrate the growth of graphene nanocrystals by molecular beam methods that employ a solid carbon source, and that can be used on a diverse class of large area dielectric sub…
Visualizing Individual Nitrogen Dopants in Monolayer Graphene
Liuyan Zhao, Rui He, Kwang Taeg Rim +15
In monolayer graphene, substitutional doping during growth can be used to alter its electronic properties. We used scanning tunneling microscopy (STM), Raman spectroscopy, x-ray sp…
Observation of magneto-phonon resonance of Dirac fermions in graphite
J. Yan, S. Goler, T. D. Rhone +5
Coherent coupling of Dirac fermion magneto-excitons with an optical phonon is observed in graphite as marked magnetic-field dependent splittings and anti-crossing behavior of the t…
