Oxygen Vacancies at Dislocation Core Modulate Plasticity in Strontium Titanate
Min‐Chul Kang, Chunxu Yan, A. M. Frisch, Xufei Fang et autres
Dislocation core chemistry in oxides critically influences mechanical behavior and functionality; yet the evolution of core chemistry during the dislocation motion in them has not been directly observed. Here, using SrTiO3 as a model material, we combine aberration-corrected scanning transmission electron microscopy …
