Scan‐Path‐ and Initial‐State‐Dependent Superdomain Switching in (111)‐Oriented PZT

Advanced Electronic Materials, Volume 12, Issue 16, 24 August 2026.
Scan trajectory and initial superdomain topology govern polarization switching in (111)‐oriented PZT. Automated AFM writing, pulsing experiments, and interferometric 3D‐PFM show that raster scans reproducibly stabilize ordered Type‐I stripe superdomains with constrained variant selection, whereas spiral trajectories generate frustrated mixed‐variant ...

Local Structural Signatures of Shear Bands in Metallic Glasses via Electron Nanodiffraction

Small Methods, Volume 10, Issue 15, 7 August 2026.
In this research, we employed scanning electron nano‐diffraction to investigate the local degree of centrosymmetry and structural anisotropy (strain) in deformed metallic glass. The study provides significant new insights into the deformation mechanisms of glassy materials, revealing the nature of local structural transformations and demonstrating how ...
