Electron-photon scattering mediated by localized plasmons: A quantitative analysis by eigen-response theory
We show that the scattering interaction between a high energy electron and a photon can be strongly enhanced by different types of localized plasmons in a nontrivial way. The scattering interaction is predicted by an eigen-response theory, numerically verified by finite-difference-time-domain simula...

| description | We show that the scattering interaction between a high energy electron and a photon can be strongly enhanced by different types of localized plasmons in a nontrivial way. The scattering interaction is predicted by an eigen-response theory, numerically verified by finite-difference-time-domain simulation, and experimentally verified by cathodoluminescence spectroscopy. We find that the scattering interaction associated with dark plasmons can be as strong as that of bright plasmons. Such a strong interaction may offer new opportunities to improve single-plasmon detection and high-resolution characterization techniques for high quality plasmonic materials. |
