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…
3D reconstruction of a million atoms by multiple-section local-orbital tomography
Liangze Mao, Jizhe Cui, Rong Yu
There exist two groups of electron microscopy methods that are capable of providing three-dimensional (3D) structural information of an object, i.e., electron tomography and depth…
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…
Accurate atomic positions via local-orbital tomography with depth-dependent interactions
Liangze Mao, Jizhe Cui, Rong Yu
Three-dimensional reconstruction of atomic structure, known as atomic electron tomography (AET), has found increasing applications in materials science. The AET has been limited to…
