Na1/2Bi1/2TiO3-based materials have been earmarked for one of the first large-volume applications lead-free piezoceramics in high-power ultrasonics. Zn2+-doping is demonstrated as a viable route to enhance thermal depolarization temperature and electromechanically harden (1-y)Na1/2Bi1/2TiO3-yBaTiO3 (NBT100yBT) with maximum achievable operating 150 °C mechanical quality factor 627 1 mole % Zn2+-...

Abstract Layered oxychalcogenide Sr 2 ZnCu (S 1- x Se ) O compounds were synthesized via a solid-state reaction. Density functional theory calculations indicate different valence band maximum, was composed of Cu 3 d –Se 4 p , while S dominated by the Zn –O hybrid orbital. Band gap decreased as Se-containing is increasing, from 2.5 eV to 2.2 eV. In contrast, electrical conductivity Se-substitute...
