Anomalous thermodiffusion of electrons in graphene
Deng Pan, Hongxing Xu, F. Javier García de Abajo
We reveal a dramatic departure of electron thermodiffusion in solids relative to the commonly accepted picture of the ideal free-electron gas model. In particular, we show that the…
Tailored nanoscale plasmon-enhanced vibrational electron spectroscopy
Luiz H. G. Tizei, Vahagn Mkhitaryan, Hugo Lourenço-Martins +12
Vibrational optical spectroscopies can be enhanced by surface plasmons to reach molecular-sized limits of detection and characterization. The level of enhancement strongly depends…
Nonlinear atom-plasmon interactions enabled by nanostructured graphene
Joel D. Cox, F. Javier García de Abajo
Electrically tunable graphene plasmons are anticipated to enable strong light-matter interactions with resonant quantum emitters. However, plasmon resonances in graphene are typica…
Fundamental Limits to the Coupling between Light and 2D Polaritons by Small Scatterers
Eduardo J. C. Dias, F. Javier García de Abajo
Polaritonic modes in two-dimensional van der Waals materials display short in-plane wavelengths compared with light in free space. As interesting as this may look from both fundame…
Tunable plasmons in ultrathin metal films
Rinu Abraham Maniyara, Daniel Rodrigo, Renwen Yu +7
The physics of electrons, photons, and their plasmonic interactions changes greatly when one or more dimensions are reduced down to the nanometer scale. For example, graphene shows…
Molecular Sensing with Tunable Graphene Plasmons
Andrea Marini, Iván Silveiro, F. Javier García de Abajo
We study the potential of graphene plasmons for spectrometer-free sensing based on surface-enhanced infrared absorption and Raman scattering. The large electrical tunability of the…
Resonant Visible Light Modulation with Graphene
Renwen Yu, Valerio Pruneri, F. Javier Garcia de Abajo
Fast modulation and switching of light at visible and near-infrared (vis-NIR) frequencies is of utmost importance for optical signal processing and sensing technologies. No fundame…
Plasmon-enhanced nonlinear wave mixing in nanostructured graphene
Joel D. Cox, F. Javier Garcia de Abajo
Localized plasmons in metallic nanostructures have been widely used to enhance nonlinear optical effects due to their ability to concentrate and enhance light down to extreme-subwa…
