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…
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…
