Investigation of Ga Doping for Non-stoichiometric Sodium Bismuth Titanate Ceramics [PDF]

Journal of Materials Science: Materials in Electronics, 2021
Abstract The electrical performance of Ga3+ doping Na0.5Bi0.5TiO3-based oxygen ion conductor was studied. The Na0.52Bi0.47Ti1−xGaxO3−δ (x = 0, 0.01, 0.015, 0.02) samples were fabricated by the means of traditional solid-state reaction. The results of AC impedance measurement show that the bulk conductivity of Na0.52Bi0.47Ti1−xGaxO3−δ samples ...

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.
