“…Here the transition energy increases linearly with magnetic field (see figure 1(b)). Such cyclotron-like resonances have been observed in cw magneto-spectroscopy experiments on single layer graphene samples on the silicon-terminated face of SiC [18,19].…”

Intraband carrier dynamics in Landau-quantized multilayer epitaxial graphene

We investigate the low-energy carrier dynamics in Landau quantized multilayer epitaxial graphene on (0001) SiC, using 14 meV photons. The THz absorption is dominated by Landau-level transitions within the conduction bands of several graphene layers with different doping. Varying the magnetic field allows us to tune the THz-induced response from induced transmission around B = 0 to induced absorption at intermediate fields (1.5 T-3.3 T) and back to induced transmission at higher fields (3.3 T-7 T). The main features of this complex response are explained by a strong dependence of the absorption on the electron temperature. Furthermore a prolonged relaxation at high fields, which is attributed to reduced scattering via optical phonons, is observed.

“…Magneto-optical spectroscopy is a powerful tool to investigate electronic properties of nodal semimetals and narrow-band-gap materials [15][16][17][18][19]. For example, this method enables experimental verification of the electronic band structure by tracing the optical transitions between the magnetic-field-induced Landau levels (LLs).…”

We present a far-infrared magneto-optical study of the gapped nodal-line semimetal ZrSiS in magnetic fields B up to 7 T. The observed field-dependent features, which represent intra-(cyclotron resonance) and interband transitions, develop as √ B in increasing field and can be consistently explained within a simple 2D Dirac band model with a gap of 26 meV and an averaged Fermi velocity of 3 × 10 5 m/s. This indicates a rather narrow distribution of these parameters along the in-plane portions of the nodal line in the Brillouin zone. A field-induced feature with an energy position that does not depend on B is also detected in the spectra. Possible origins of this feature are discussed.

“…Graphene plasmonics 1,2 is a rapidly growing branch of research which aims at exploiting the interaction of infrared light with the so-called "Dirac plasmons" (DPs) [3][4][5][6] for a variety of applications ranging from photodetectors 7,8 to biosensors. 9 DPs, the self-sustained density oscillations of the two-dimensional (2D) electron liquid in a doped graphene sheet, 10,11 have been studied experimentally with a variety of spectroscopic methods.…”

Impact of disorder on Dirac plasmon losses

et al. 2013

View full text Add to dashboard Cite

Recent scattering-type scanning near-field optical spectroscopy (s-SNOM) experiments on single-layer graphene have reported Dirac plasmon lifetimes that are substantially shorter than the dc transport scattering time τ tr . We argue that this discrepancy arises from the fact that the plasmon lifetime is fundamentally different from τ tr since it is controlled by the imaginary part of the current-current linear response function at finite momentum and frequency. Taking this into account, we show that a minimal theory of the extrinsic lifetime of Dirac plasmons due to scattering against charged impurities yields a plasmon damping rate which is in good agreement with s-SNOM experimental results.
