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…
Revealing time characteristics of optical excitations in dielectric and plasmonic structures through cathodoluminescence interferometry
Evelijn Akerboom, Hirohsi Sugimoto, Minoru Fujii +5
Cathodoluminescence (CL) spectroscopy provides access to optical excitations with nanometer spatial resolution, but direct time-resolved measurements of optical resonances remain c…
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…
Toward Optimum Coupling between Free Electrons and Confined Optical Modes
Valerio Di Giulio, Evelijn Akerboom, Albert Polman +1
Free electrons are unique tools to probe and manipulate nanoscale optical fields with emerging applications in ultrafast spectromicroscopy and quantum metrology. However, advances…
