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…
Observation of non-volatile anomalous Nernst effect in altermagnet with collinear Néel vector
Lei Han, Xizhi Fu, Wenqing He +11
Anomalous Nernst effect (ANE), a widely investigated transverse thermoelectric effect that converts waste heat into electrical energy with remarkable flexibility and integration ca…
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…
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…
