Very-High Dynamic Range, 10,000 frames/second Pixel Array Detector for Electron Microscopy
Hugh T. Philipp, Mark W. Tate, Katherine S. Shanks +10
Precision and accuracy of quantitative scanning transmission electron microscopy (STEM) methods such as ptychography, and the mapping of electric, magnetic and strain fields depend…
Data-Driven Electron Microscopy: Electron Diffraction Imaging of Materials Structural Properties
Jian-Min Zuo, Renliang Yuan, Yu-Tsun Shao +5
Transmission electron diffraction is a powerful and versatile structural probe for the characterization of a broad range of materials, from nanocrystalline thin films to single cry…
A room temperature polar ferromagnetic metal
Hongrui Zhang, Yu-Tsun Shao, Rui Chen +15
The advent of long-range magnetic order in non-centrosymmetric compounds has stimulated interest in the possibility of exotic spin transport phenomena and topologically protected s…
Ferroelectricity in Polar ScAlN/GaN Epitaxial Semiconductor Heterostructures
Joseph Casamento, Ved Gund, Hyunjea Lee +11
Room temperature ferroelectricity is observed in lattice-matched ~18% ScAlN/GaN heterostructures grown by molecular beam epitaxy on single-crystal GaN substrates. The epitaxial fil…
Emergence of a noncollinear magnetic state in twisted bilayer CrI3
Yang Xu, Ariana Ray, Yu-Tsun Shao +8
The emergence of two-dimensional (2D) magnetic crystals and moiré engineering has opened the door for devising new magnetic ground states via competing interactions in moiré superl…
Cepstral Scanning Transmission Electron Microscopy Imaging of Severe Lattice Distortions
Yu-Tsun Shao, Renliang Yuan, Haw-Wen Hsiao +3
The development of four-dimensional (4D) scanning transmission electron microscopy (STEM) using fast detectors has opened-up new avenues for addressing some of long-standing challe…
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…
Emergent chirality in a polar meron to skyrmion phase transition
Yu-Tsun Shao, Sujit Das, Zijian Hong +10
Polar skyrmions are predicted to emerge from the interplay of elastic, electrostatic and gradient energies, in contrast to the key role of the anti-symmetric Dzyalozhinskii-Moriya…
