Electronic excitations and electron-phonon coupling in bulk graphite through Raman scattering in high magnetic fields
P. Kossacki, C. Faugeras, M. Kühne +6
We use polarized magneto-Raman scattering to study purely electronic excitations and the electron-phonon coupling in bulk graphite. At a temperature of 4.2 K and in magnetic fields…
Cyclotron motion in the vicinity of a Lifshitz transition in graphite
M. Orlita, P. Neugebauer, C. Faugeras +4
Graphite, a model (semi)metal with trigonally warped bands, is investigated with magneto-absorption experiment and viewed as an electronic system in the vicinity of the Lifshitz tr…
Integer Quantum Hall Effect in Trilayer Graphene
A. Kumar, W. Escoffier, J. M. Poumirol +7
The Integer Quantum Hall Effect (IQHE) is a distinctive phase of two-dimensional electronic systems subjected to a perpendicular magnetic field. Thus far, the IQHE has been observe…
Magneto-Raman scattering of graphene on graphite: Electronic and phonon excitations
C. Faugeras, M. Amado, P. Kossacki +5
Magneto-Raman scattering experiments from the surface of graphite reveal novel features associated to purely electronic excitations which are observed in addition to phonon-mediate…
Carrier scattering from dynamical magneto-conductivity in quasi-neutral epitaxial graphene
M. Orlita, C. Faugeras, R. Grill +6
The energy-dependence of the electronic scattering time is probed by Landau level spectroscopy in quasi neutral multilayer epitaxial graphene. From the Landau levels broadening we…
