Topological textures and emergent altermagnetic signatures in ultrathin BiFeO3
George Fratian, Maya Ramesh, Xinyan Li +23
Magnetoelectric multiferroics, materials with intrinsically coupled electric polarization and magnetic order, promise ultralow-power switching, nonvolatile memory, and energy-effic…
Discovery of a new weberite-type antiferroelectric: La3NbO7
Louis Alaerts, Jesse Schimpf, Xinyan Li +7
Antiferroelectrics are antipolar materials which possess an electric field-induced phase transition to a polar, ferroelectric phase and offer significant potential for sensing/actu…
Deep sub-Ã ngstrom imaging of 2D materials with a high dynamic range detector
Yi Jiang, Zhen Chen, Yimo Han +9
Aberration-corrected optics have made electron microscopy at atomic-resolution a widespread and often essential tool for nanocharacterization. Image resolution is dominated by beam…
Imaging Polarity in Two Dimensional Materials by Breaking Friedel's Law
Pratiti Deb, Michael C. Cao, Yimo Han +5
Friedel's law guarantees an inversion-symmetric diffraction pattern for thin, light materials where a kinematic approximation or a single-scattering model holds. Typically, breakin…
Preserving Surface Strain in Nanocatalysts via Morphology Control
Chuqiao Shi, Zhihua Cheng, Alberto Leonardi +4
Engineering strain critically affects the properties of materials and has extensive applications in semiconductors and quantum systems. However, the deployment of strain-engineered…
Strain Mapping of Two-Dimensional Heterostructures with Sub-Picometer Precision
Yimo Han, Kayla Nguyen, Michael Cao +7
Next-generation, atomically thin devices require in-plane, one-dimensional heterojunctions to electrically connect different two-dimensional (2D) materials. However, the lattice mi…
