Enhanced graphene nonlinear response through geometrical plasmon focusing
Saavedra, J. R. M.; García de Abajo, F. Javier (AIP, 2018-01-01)
Article
Open AccessWe propose a simple approach to couple light into graphene plasmons and focus these excitations at focal spots of a size determined by the plasmon wavelength, thus producing high optical field enhancement that boosts the ... -
Phonon excitation by electron beams in nanographenes
Saavedra, J. R. M.; García de Abajo, Francisco Javier (APS, 2015-09-30)
Article
Open AccessElectron beams have the ability of exciting vibrational modes (phonons) in molecules and nanoclusters, which can be currently probed with atomic spatial resolution through electron energy-loss spectroscopy (EELS). This ... -
Smith-Purcell radiation emission in aperiodic arrays
Saavedra, J. R. M.; Castells-Graells, D.; García de Abajo, F. Javier (APS, 2016-07-13)
Article
Open AccessWe study the Smith-Purcell light emission produced by electrons moving parallel to linear aperiodic particle arrays. This constitutes a generalization of this type of phenomenon from periodic to aperiodic structures. As ...
