Strain Tuning the Kinetics of Topotactic Phase Transitions in Epitaxial Oxide Films

We report the kinetics of the topotactic brownmillerite–perovskite phase transition in epitaxial strontium cobaltite (SrCoOx) thin films. Our findings reveal asymmetric switching kinetics between the oxygen‐deficient SrCoO2.5 and oxygen‐rich SrCoO3 phases, driven by the epitaxial strain state. Using phase‐field modelin...

Symbolic Predicate-Guided Language Agents for Inverse Design of Perovskite Oxides

This work introduces a domain specific language (DSL)-guided strategy to improve the reasoning and design capability of LLM agents by translating natural language design rules into symbolic predicates encoded in a predefined chemistry DSL, and developed a multi-agent materials design framework.
