Impact of Many-Body Effects on Landau Levels in Graphene
J. Sonntag, S. Reichardt, L. Wirtz +4
We present magneto-Raman spectroscopy measurements on suspended graphene to investigate the charge carrier density-dependent electron-electron interaction in the presence of Landau…
Tailoring mechanically-tunable strain fields in graphene
M. Goldsche, J. Sonntag, T. Khodkov +7
There are a number of theoretical proposals based on strain engineering of graphene and other two-dimensional materials, however purely mechanical control of strain fields in these…
Raman Spectroscopy of Graphene
Sven Reichardt, Ludger Wirtz
Raman spectroscopy of graphene is reviewed from a theoretical perspective. After an introduction of the building blocks (electronic band structure, phonon dispersion, electron-phon…
Quantum interference effects in resonant Raman spectroscopy of single- and triple-layer MoTe from first principles
Henrique P. C. Miranda, Sven Reichardt, Guillaume Froehlicher +3
We present a combined experimental and theoretical study of resonant Raman spectroscopy in single- and triple-layer MoTe. Raman intensities are computed entirely from first pri…
Ab initio calculation of the peak intensity of graphene: Combined study of the laser and Fermi energy dependence and importance of quantum interference effects
Sven Reichardt, Ludger Wirtz
We present the results of a diagrammatic, fully ab initio calculation of the peak intensity of graphene. The flexibility and generality of our approach enables us to go beyond…
