The complex structural mechanisms behind strain curves in bismuth sodium titanate–barium titanate [PDF]
Applied Physics Letters, 2020 In this work, the lead-free composition (1-x)Bi0.5Na0.5TiO3–xBaTiO3 (BNT–BT) with x = 0.12 was investigated using in situ Synchrotron x-ray powder diffraction. With the applied electric field, the pseudo-cubic relaxor phase reversibly transforms to a ferroelectric state. The reversibility is still preserved after 104 bipolar electric field cycles.

Boosting Photo‐Pyroelectric Effect via Tunable Polarization and Interfacial Defect Engineering
Advanced Science, Volume 13, Issue 25, 4 May 2026.This study reports Ba(Ti0.85Zr0.15)O3 nanocatalysts with enhanced polarization and oxygen‐vacancy‐rich interfaces for efficient NIR‐II photo‐pyroelectric therapy. Zr doping boosts the pyroelectric coefficient and accelerates polarization switching, while oxygen vacancies improve photothermal conversion and surface reactivity.
