Spectrometer-Free Electron Spectromicroscopy
F. Javier García de Abajo, Cruz I. Velasco
We introduce an approach for performing spectrally resolved electron microscopy without the need for an electron spectrometer. The method involves an electron beam prepared as a co…
Roadmap for Photonics with 2D Materials
F. Javier García de Abajo, D. N. Basov, Frank H. L. Koppens +145
Triggered by the development of exfoliation and the identification of a wide range of extraordinary physical properties in self-standing films consisting of one or few atomic layer…
Roadmap for Quantum Nanophotonics with Free Electrons
F. Javier García de Abajo, Albert Polman, Cruz I. Velasco +44
Over the past century, continuous advancements in electron microscopy have enabled the synthesis, control, and characterization of high-quality free-electron beams. These probes ca…
Free-Space Optical Modulation of Free Electrons in the Continuous-Wave Regime
Cruz I. Velasco, F. Javier García de Abajo
The coherent interaction between free electrons and optical fields can produce free-electron compression and push the temporal resolution of ultrafast electron microscopy to the at…
Ultrafast momentum-resolved visualization of the interplay between phonon-mediated scattering and plasmons in graphite
Francesco Barantani, Rémi Claude, Fadil Iyikanat +7
Scattering between individual charges and collective modes in materials governs fundamental phenomena such as electrical resistance, energy dissipation, switching between different…
Anisotropic Second Harmonic Generation From Monocrystalline Gold Flakes
Sergejs Boroviks, Torgom Yezekyan, Álvaro Rodríguez Echarri +5
Noble metals with well-defined crystallographic orientation constitute an appealing class of materials for controlling light-matter interactions on the nanoscale. Nonlinear optical…
Spontaneous and Stimulated Electron-Photon Interactions in Nanoscale Plasmonic Near Fields
