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…
Efficient Sorting of Free Electron Orbital Angular Momentum
Benjamin J. McMorran, Tyler R. Harvey, Martin P. J. Lavery
We propose a method for sorting electrons by orbital angular momentum (OAM). Several methods now exist to prepare electron wavefunctions in OAM states, but no technique has been de…
A streamlined approach to mapping the magnetic induction of skyrmionic materials
Jordan J. Chess, Sergio A. Montoya, Tyler R. Harvey +5
Recently, Lorentz transmission electron microscopy (LTEM) has helped researchers advance the emerging field of magnetic skyrmions. These magnetic quasi-particles, composed of topol…
A Stern-Gerlach-like approach to electron orbital angular momentum measurement
Tyler R. Harvey, Benjamin J. McMorran
Many methods now exist to prepare free electrons into orbital angular momentum states, and the predicted applications of these electron states as probes of materials and scattering…
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…
