Synthesizing free-electron wave functions by stimulated near-field interactions
Álvaro Rodríguez Echarri, Albert Polman
Stimulated electron-optical-near-field interactions imprint a coherent, phase-coherent modulation on the wave function of a free electron, of which the free-space dispersion subseq…
Studying electron beam coherence using plasmon interference
Evelijn Akerboom, F. Javier García de Abajo, Albert Polman
Energetic electrons create distinct cathodoluminescence (CL) angular distributions upon interaction with dielectric and plasmonic nanostructures, providing valuable information on…
Determining Electron Beam Lateral Coherence in a Scanning Electron Microscope Using Electron Diffraction
Evelijn Akerboom, Fatemeh Kiani, Giulia Tagliabue +4
We develop and characterize scanning transmission electron microscopy (STEM) capabilities within a scanning electron microscope (SEM) to investigate the effective lateral coherence…
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…
Angle-resolved cathodoluminescence spectroscopy
T. Coenen, E. J. R Vesseur, A. Polman
We present a novel cathodoluminescence spectroscopy technique which combines a deep subwavelength excitation resolution with angle-resolved detection capabilities. The cathodolumin…
