Landau level spectroscopy of electron-electron interactions in graphene
C. Faugeras, S. Berciaud, P. Leszczynski +11
We present magneto-Raman scattering studies of electronic inter Landau level excitations in quasi-neutral graphene samples with different strengths of Coulomb interaction. The band…
Magnetic field tuning of exciton polaritons in a semiconductor microcavity
B. Pietka, D. Zygmunt, M. Krol +11
We detail the influence of a magnetic field on exciton-polaritons inside a semiconductor microcavity. Magnetic field can be used as a tuning parameter for exciton and photon resona…
Critical point for the CAF-F phase transition at charge neutrality in bilayer graphene
S. Pezzini, C. Cobaleda, B. A. Piot +2
We report on magneto-transport measurements up to 30 T performed on a bilayer graphene Hall bar, enclosed by two thin hexagonal boron nitride flakes. Our high mobility sample exhib…
Probing electronic excitations in mono- to pentalayer graphene by micro-magneto-Raman spectroscopy
Stéphane Berciaud, Marek Potemski, Clément Faugeras
We probe electronic excitations between Landau levels in freestanding layer graphene over a broad energy range, with unprecedented spectral and spatial resolution, using micro-…
Hyperfine coupling and spin polarization in the bulk of the topological insulator BiSe
S. Mukhopadhyay, S. Krämer, H. Mayaffre +10
Nuclear magnetic resonance (NMR) and transport measurements have been performed at high magnetic fields and low temperatures in a series of -type BiSe crystals. In l…
Second order resonant Raman scattering in single layer tungsten disulfide (WS)
A. A. Mitioglu, P. Plochocka, G. Deligeorgis +3
Resonant Raman spectra of single layer WS flakes are presented. A second order Raman peak (2LA) appears under resonant excitation with a separation from the E mode…
Hierarchy of Hofstadter states and replica quantum Hall ferromagnetism in graphene superlattices
G. L. Yu, R. V. Gorbachev, J. S. Tu +16
Self-similarity and fractals have fascinated researchers across various disciplines. In graphene placed on boron nitride and subjected to a magnetic field, self-similarity appears…
Plasmonic terahertz detectors based on a high-electron mobility GaAs/AlGaAs heterostructure
M. Białek, A. M. Witowski, M. Orlita +6
In order to characterize magnetic-field (B) tunable THz plasmonic detectors, spectroscopy experiments were carried out at liquid helium temperatures and high magnetic fields on dev…
Unintentional high density p-type modulation doping of a GaAs/AlAs core-multi-shell nanowire
J. Jadczak, P. Plochocka, A. Mitioglu +8
Achieving significant doping in GaAs/AlAs core/shell nanowires (NWs) is of considerable technological importance but remains a challenge due to the amphoteric behavior of the dopan…
Electrical switch to the resonant magneto-phonon effect in graphene
P. Leszczynski, Z. Han, A. A. L. Nicolet +7
We report a comprehensive study of the tuning with electric fields of the resonant magneto-exciton optical phonon coupling in gated graphene. For magnetic fields around …
