A Geometric Pathway for Tuning Ferroelectric Properties via Polar State Reconfiguration
Hao-Cheng Thong, Bo Wu, Fan Hu +7
We report the discovery of a geometric pathway for tuning ferroelectric properties through thermally driven reconfiguration between coexisting polar states in Li-substituted NaNbO3…
Machine learning-enabled atomistic insights into phase boundary engineering of solid-solution ferroelectrics
Weiru Wen, Fan-Da Zeng, Ben Xu +4
Atomistic control of phase boundaries is crucial for optimizing the functional properties of solid-solution ferroelectrics, yet their microstructural mechanisms remain elusive. Her…
Origin of Increased Curie Temperature in Lithium-Substituted Ferroelectric Niobate Perovskite: Enhancement of the Soft Polar Mode
Hao-Cheng Thong, Fang-Zhou Yao, Xian-Xian Cai +7
The functionality of ferroelectrics is often constrained by their Curie temperature, above which depolarization occurs. Lithium (Li) is the only experimentally known substitute tha…
