Boosting Photo-Pyroelectric Effect via Tunable Polarization and Interfacial Defect Engineering. [PDF]
Adv Sci (Weinh)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.
