Exciton-assisted electron tunneling in van der Waals heterostructures
Lujun Wang, Sotirios Papadopoulos, Fadil Iyikanat +8
The control of elastic and inelastic electron tunneling relies on materials with well defined interfaces. Van der Waals materials made of two-dimensional constituents form an ideal…
Coherent Smith-Purcell -Ray Emission
Kamran Akbari, Simone Gargiulo, Fabrizio Carbone +1
We investigate the Smith-Purcell emission produced by electron- or ion-beam-driven coherent excitation of nuclei arranged in periodic crystal lattices. The excitation and subsequen…
Approaching the Purcell factor limit with whispering-gallery hyperbolic phonon polaritons in hBN nanotubes
Xiangdong Guo, Ning Li, Xiaoxia Yang +9
Enhanced light-matter interaction at the nanoscale is pivotal in the foundation of nonlinear optics, quantum optics, and nanophotonics, which are essential for a vast range of appl…
Ultrafast Momentum-Resolved Probing of Plasmon Thermal Dynamics with Free Electrons
Vahagn Mkhitaryan, Eduardo J. C. Dias, Fabrizio Carbone +1
Current advances in ultrafast electron microscopy make it possible to combine optical pumping of a nanostructure and electron beam probing with subångstrom and femtosecond spatiote…
Optical Excitations with Electron Beams: Challenges and Opportunities
F. Javier García de Abajo, Valerio Di Giulio
Free electron beams such as those employed in electron microscopes have evolved into powerful tools to investigate photonic nanostructures with an unrivaled combination of spatial…
Electron Beam Aberration Correction Using Optical Near Fields
Andrea Konečná, F. Javier García de Abajo
The interaction between free electrons and optical near fields is attracting increasing attention as a way to manipulate the electron wave function in space, time, and energy. Rely…
