Strong plasmon reflection at nanometer-size gaps in monolayer graphene on SiC
Jianing Chen, Maxim L. Nesterov, Alexey Yu. Nikitin +12
We employ tip-enhanced infrared near-field microscopy to study the plasmonic properties of epitaxial quasi-free-standing monolayer graphene on silicon carbide. The near-field image…
Annealing-induced magnetic moments detected by spin precession measurements in epitaxial graphene on SiC
Bastian Birkner, Daniel Pachniowski, Andreas Sandner +6
We present results of non-local and three terminal (3T) spin precession measurements on spin injection devices fabricated on epitaxial graphene on SiC. The measurements were perfor…
Small scale rotational disorder observed in epitaxial graphene on SiC(0001)
Andrew L. Walter, Aaron Bostwick, Florian Speck +8
Interest in the use of graphene in electronic devices has motivated an explosion in the study of this remarkable material. The simple, linear Dirac cone band structure offers a uni…
Classical to quantum crossover of the cyclotron resonance in graphene: A study of the strength of intraband absorption
M. Orlita, I. Crassee, C. Faugeras +7
We report on absolute magneto-transmission experiments on highly-doped quasi-free-standing epitaxial graphene targeting the classical-to-quantum crossover of the cyclotron resonanc…
Effective screening and the plasmaron bands in Graphene
Andrew L. Walter, Aaron Bostwick, Ki-Joon Jeon +10
Electron-plasmon coupling in graphene has recently been shown to give rise to a "plasmaron" quasiparticle excitation. The strength of this coupling has been predicted to depend on…
Terahertz radiation driven chiral edge currents in graphene
J. Karch, C. Drexler, P. Olbrich +14
We observe photocurrents induced in single layer graphene samples by illumination of the graphene edges with circularly polarized terahertz radiation at normal incidence. The photo…
Highly p-doped graphene obtained by fluorine intercalation
Andrew L. Walter, Ki-Joon Jeon, Aaron Bostwick +8
We present a method for decoupling epitaxial graphene grown on SiC(0001) by intercalation of a layer of fluorine at the interface. The fluorine atoms do not enter into a covalent b…
The quasi-free-standing nature of graphene on H-saturated SiC(0001)
F. Speck, J. Jobst, F. Fromm +5
We report on an investigation of quasi-free-standing graphene on 6H-SiC(0001) which was prepared by intercalation of hydrogen under the buffer layer. Using infrared absorption spec…
Giant Faraday rotation in single- and multilayer graphene
Iris Crassee, Julien Levallois, Andrew L. Walter +6
Optical Faraday rotation is one of the most direct and practically important manifestations of magnetically broken time-reversal symmetry. The rotation angle is proportional to the…
