Revealing Nanoscale Confinement Effects on Hyperbolic Phonon Polaritons with an Electron Beam
Andrea Konečná, Jiahan Li, James H. Edgar +2
Hyperbolic phonon polaritons (HPhPs) in hexagonal boron nitride (hBN) enable the direct manipulation of mid-infrared light at nanometer scales, many orders of magnitude below the f…

Modulation of Cathodoluminescence Emission by Interference with External Light
Valerio Di Giulio, Ofer Kfir, Claus Ropers +1
Spontaneous processes triggered in a sample by free electrons are commonly regarded as incoherent, and therefore unable to interfere with external light sources. Here, we challenge…
