Structural dynamics probed by high-coherence electron pulses
Armin Feist, Gero Storeck, Sascha Schäfer +1
Ultrafast measurement technology provides essential contributions to our microscopic understanding of the properties and functions of solids and nanostructures. Atomic-scale vistas…
Spontaneous and Stimulated Electron-Photon Interactions in Nanoscale Plasmonic Near Fields
Matthias Liebtrau, Murat Sivis, Armin Feist +6
We demonstrate spatially-resolved measurements of spontaneous and stimulated electron-photon interactions in nanoscale optical near fields using electron energy-loss spectroscopy (…
Probing chirality with inelastic electron-light scattering
Tyler R. Harvey, Jan-Wilke Henke, Ofer Kfir +4
Circular dichroism spectroscopy is an essential technique for understanding molecular structure and magnetic materials, but spatial resolution is limited by the wavelength of light…
High-purity free-electron momentum states prepared by three-dimensional optical phase modulation
Armin Feist, Sergey V. Yalunin, Sascha Schäfer +1
We demonstrate the quantized transfer of photon energy and transverse momentum to a high-coherence electron beam. In an ultrafast transmission electron microscope, a three-dimensio…
