Electron ptychography achieves atomic-resolution limits set by lattice vibrations
Zhen Chen, Yi Jiang, Yu-Tsun Shao +7
Transmission electron microscopes use electrons with wavelengths of a few picometers, potentially capable of imaging individual atoms in solids at a resolution ultimately set by th…
Dimensionality-induced change in topological order in multiferroic oxide superlattices
Megan E. Holtz, Elliot S. Padgett, Rachel Steinhardt +5
We construct ferroelectric (LuFeO3)m/(LuFe2O4) superlattices with varying index m to study the effect of confinement on topological defects. We observe a thickness-dependent transi…
Imaging Polarity in Two Dimensional Materials by Breaking Friedel's Law
Pratiti Deb, Michael C. Cao, Yimo Han +5
Friedel's law guarantees an inversion-symmetric diffraction pattern for thin, light materials where a kinematic approximation or a single-scattering model holds. Typically, breakin…
The Exit-Wave Power-Cepstrum Transform for Scanning Nanobeam Electron Diffraction: Robust Strain Mapping at Subnanometer Resolution and Subpicometer Precision
Elliot Padgett, Megan E. Holtz, Paul Cueva +4
Scanning nanobeam electron diffraction (NBED) with fast pixelated detectors is a valuable technique for rapid, spatially resolved mapping of lattice structure over a wide range of…
Revealing the nanoparticle composition of Edvard Munch's The Scream, and implications for paint alteration in iconic early 20th century artworks
Barnaby D. A. Levin, Adam C. Finnefrock, Alyssa M. Hull +7
A major motivation for the scientific study of artworks is to understand their states of preservation and ongoing degradation mechanisms. This enables preservation strategies to be…
Electrical half-wave rectification at ferroelectric domain walls
J. Schaab, S. H. Skjærvø, S. Krohns +10
Ferroelectric domain walls represent multifunctional 2D-elements with great potential for novel device paradigms at the nanoscale. Improper ferroelectrics display particularly prom…
