Operando spectro-ptychography reveals dynamical charge-storage and degradation pathways in redox-active electrodes
Xiao Zhao, Yuchen Cao, Evan Z Carlson +13
Electrochemical reactions at buried electrode-electrolyte interfaces govern how redox-active materials store and release energy. However, these reactions are difficult to visualize…
Three-dimensional imaging of individual carbon atoms
Na Yeon Kim, Hanfeng Zhong, Jianhua Zhang +13
Carbon is fundamental to science and technology due to its diverse bonding configurations, structural versatility, and essential role in defining the mechanical, chemical, electron…
Imaging thick objects with deep-sub-angstrom resolution and deep-sub-picometer precision
Wenfeng Yang, Haozhi Sha, Jizhe Cui +1
Size effects are ubiquitous in the structural, mechanical, and physical properties of materials, making it highly desirable to study the intrinsic properties of thick objects throu…
High-quality imaging of large areas through path-difference ptychography
Jizhe Cui, Yi Zheng, Kang Sun +3
Tilting planar samples for multi-zone-axes observation is a routine procedure in electron microscopy. However, this process invariably introduces optical path differences in the el…
Imaging, counting, and positioning single interstitial atoms in solids
Jizhe Cui, Haozhi Sha, Liangze Mao +3
Interstitial atoms are ubiquitous in solids and they are widely incorporated into materials to tune their lattice structure, electronic transportation, and mechanical properties. B…
Polar vortex hidden in twisted bilayers of paraelectric SrTiO3
Haozhi Sha, Yixuan Zhang, Yunpeng Ma +6
Polar topologies, such as vortex and skyrmion, have attracted significant interest due to their unique physical properties and promising applications in high-density memory devices…
Information limit of 15 pm achieved with bright-field ptychography
Haozhi Sha, Jizhe Cui, Wenfeng Yang +1
It is generally assumed that a high spatial resolution of a microscope requires a large numerical aperture of the imaging lens or detector. In this study, the information limit of…
Three-dimensional imaging of buried heterointerfaces
Colum M. O'Leary, Haozhi Sha, Jianhua Zhang +6
We report three-dimensional (3D) structure determination of a twisted hexagonal boron nitride (h-BN) heterointerface from a single-view data set using multislice ptychography. We i…
Atomic-resolution imaging of magnetism via ptychographic phase retrieval
Jizhe Cui, Haozhi Sha, Wenfeng Yang +1
Atomic-scale characterization of spin textures in solids is essential for understanding and tuning properties of magnetic materials and devices. While high-energy electrons are emp…
