Atomically thin silver films for enhanced nanoscale nonlinear optics
Philipp K. Jenke, Saad Abdullah, Andrew P. Weber +8
The inherently weak nonlinear optical response of bulk materials remains a fundamental limitation in advancing photonic technologies. Nanophotonics addresses this challenge by tail…

Real-time surface plasmon polariton propagation in silver nanowires
Wenhua Zhao, Ãlvaro RodrÃguez Echarri, Alberto Eljarrat +7
Electron microscopy techniques such as electron energy-loss spectroscopy (EELS) facilitate the spatio-spectral characterization of plasmonic nanostructures. In this work, a time-de…

Electron beams traversing spherical nanoparticles: analytic and numerical treatment
P. Elli Stamatopoulou, Wenhua Zhao, Ãlvaro RodrÃguez Echarri +4
We present an analytic, Mie theory-based solution for the energy-loss and the photon-emission probabilities in the interaction of spherical nanoparticles with electrons passing nea…
