Cloning of Dirac fermions in graphene superlattices
L. A. Ponomarenko, R. V. Gorbachev, G. L. Yu +15
Lateral superlattices have attracted major interest as this may allow one to modify spectra of two dimensional electron systems and, ultimately, create materials with tailored elec…
Magneto-absorption spectra of hydrogen-like yellow exciton series in cuprous oxide: excitons in strong magnetic fields
Sergey L. Artyukhin, Dmitry Fishman, Clément Faugeras +4
We study the absorption spectra of the yellow excitons in CuO in high magnetic fields using polarization-resolved optical absorption measurements with a high frequency resoluti…
Circular dichroism of magneto-phonon resonance in doped graphene
P. Kossacki, C. Faugeras, M. Kühne +6
Polarization resolved, Raman scattering response due to E phonon in monolayer graphene has been investigated in magnetic fields up to 29 T. The hybridization of the E…
Resonant Excitation of Graphene K-Phonon and Intra-Landau-Level Excitons in Magneto-Optical Spectroscopy
M. Orlita, Liang Z. Tan, M. Potemski +5
Precise infrared magnetotransmission experiments have been performed in magnetic fields up to 32 T on a series of multilayer epitaxial graphene samples. We observe changes in the s…
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…
