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…

Controlling free electrons with optical whispering-gallery modes

Ofer Kfir, Hugo Lourenço-Martins, Gero Storeck +5

Free-electron beams serve as uniquely versatile probes of microscopic structure and composition, and have repeatedly revolutionized atomic-scale imaging, from solid-state physics t…

Probing Light Atoms at Sub-nanometer Resolution: Realization of Scanning Transmission Electron Microscope Holography

Fehmi S. Yasin, Tyler R. Harvey, Jordan J. Chess +4

Atomic resolution imaging in transmission electron microscopy (TEM) and scanning TEM (STEM) of light elements in electron-transparent materials has long been a challenge. Biomolecu…

Interpretable and efficient contrast in scanning transmission electron microscopy with a diffraction grating beamsplitter

Tyler R. Harvey, Fehmi S. Yasin, Jordan J. Chess +9

Efficient imaging of biomolecules, 2D materials and electromagnetic fields depends on retrieval of the phase of transmitted electrons. We demonstrate a method to measure phase in a…

Demonstration of electron helical dichroism as a local probe of chirality

Tyler R. Harvey, Jordan S. Pierce, Jordan J. Chess +1

We report observation of electron helical dichroism on a material with chiral structure. In analogy with circular dichroism, a common technique for molecular structural fingerprint…
