Ternary solid solutions of (1 − x )(0.8Bi 0.5 Na TiO 3 –0.2Bi K )– NaNbO (BNKT– NN) lead‐free piezoceramics were fabricated using a conventional solid‐state reaction method. Pure BNKT composition exhibited an electric‐field‐induced irreversible structural transition from pseudocubic to ferroelectric rhombohedral phase at room temperature. Accompanied with the ferroelectric‐to‐relaxor temperature T F‐R shifted down below as substitution NN , compositionally induced nonergodic‐to‐ergodic...
Schematic diagram of the proposed gas-sensing mechanism for p-type BiFeO<sub>3</sub> based gas sensor: (a) and (c) in air, (b) (d) reducing gas, (e) simplified equivalent circuit.
The operating temperature of ZnO-based gas sensors has been decreased, which is attributed to the formation NiO/ZnO p–n heterostructures.
Compared to the bulk-CN, quasi-2D-CN possesses a unique electronic structure, enlarged bandgap, prolonged lifetime, increased surface area and enhanced transport, exhibits highly efficient hydrogen production from water under visible light.
Abstract Recent studies have shown that piezoelectric materials containing defects can exhibit significant electrobending, leading to ultrahigh apparent strain and asymmetric strain‐electric field curves. The mechanism of electrobending deformation is particularly important how achieve in ferroelectric ceramics a research topic. In this work, sodium bismuth titanate‐based (NBT) ceramics, typical lead‐free ferroelectrics, are designed demonstrate the correlation between poling process...
Pure perovskite K 0.5 Na NbO 3 – x SrTiO ( = 0.16, 0.17, 0.18, and 0.19) ceramics were prepared by using a solid‐state reaction process. The optically transparent for visible near‐infrared wavelengths. Then, high tunability (24.1%) low dielectric loss (0.016) the 0.18 sample indicated could be used in tunable devices. Lorentz‐type relation fitting temperature dependence of permittivity showed that these had typical relaxor behavior, polar nanoregions related to properties. nonlinear behavior...
(1-x)(0.8Bi1/2Na1/2TiO3-0.2Bi1/2K1/2TiO3)-xBi(Ni2/3Nb1/3)O3 (BNKT-xBNN) solid solution ceramics were fabricated by high temperature solid-state reaction method. All the compositions possess relaxor ferroelectric features, among which ergodic BNKT-0.02BNN exhibits large repeatable electrostrain value Suni = 0.51% at electric field of 65 kV/cm, with piezoelectric stain coefficient d33∗ 890 pm/V 45 while non-ergodic present unrepeatable strain response. Based on field-composition phase diagram,...
