High performance bilayer-graphene Terahertz detectors
Davide Spirito, Dominique Coquillat, Sergio L. De Bonis +7
We report bilayer-graphene field effect transistors operating as THz broadband photodetectors based on plasma-waves excitation. By employing wide-gate geometries or buried gate con…
Raman spectroscopy as a versatile tool for studying the properties of graphene
Andrea C. Ferrari, Denis M. Basko
Raman spectroscopy is an integral part of graphene research. It is used to determine the number and orientation of layers, the quality and types of edge, and the effects of perturb…
Non-equilibrium dynamics of photo-excited electrons in graphene: collinear scattering, Auger processes, and the impact of screening
Andrea Tomadin, Daniele Brida, Giulio Cerullo +2
We present a combined analytical and numerical study of the early stages (sub-100fs) of the non-equilibrium dynamics of photo-excited electrons in graphene. We employ the semiclass…
Controlling Sub-nm Gaps in Plasmonic Dimers using Graphene
Jan Mertens, Anna L. Eiden, Daniel O. Sigle +9
Graphene is used as the thinnest possible spacer between gold nanoparticles and a gold substrate. This creates a robust, repeatable, and stable sub-nanometre gap for massive plasmo…
Effects of Electron-Electron Interactions on Electronic Raman Scattering of Graphite in High Magnetic Fields
Y. Ma, Y. Kim, N. G. Kalugin +5
We report the observation of strongly temperature-dependent, asymmetric spectral lines in electronic Raman scattering spectra of graphite in a high magnetic field up to 45 T applie…
