Different substitution mechanisms provide ideas toward future improvement of lead-free (Ba,Ca)(Zr,Ti)O3 piezoelectric ceramics, including the electrocaloric effect, fluorescence, and energy storage. It is established that axial and radial element segregation differently influences electrical properties of 0.68Pb(Mg1/3Nb2/3)0.32PbTiO3 (PMN-32PT for short) single crystals. While the electrical properties along the axial direction strongly depend on the PbTiO3 content, the electrical properties along the axial direction are mainly determined by the ratio of Nb and Mg. On the other hand, Fe-substitution of PMN-32PT crystals lead to an enhancement of the coercive field due to wall pinning induced by charged defect dipoles. It is also found, that capacitors based on Pt/Na0.5Bi0.5TiO3/La0.5Sr0.5CoO3 thin films display good fatigue resistance and retention. Another lead-free thin film capacitor fabricated from Ba0.3Sr0.7Zr0.18Ti0.82 features a low leakage current density and high breakdown strength. Such capacitors are essential for energy storage. Furthermore, an enhanced electrocaloric effect on 0.73Pb(Mg1/3Nb2/3)0.27PbTiO3 single crystals is demonstrated. This effect is promising for novel solid-state cooling systems. 606 $aResearch & information: general$2bicssc 610 $aacceptor doping 610 $aBridgman technique 610 $aBSZT thin films 610 $acapacitance properties 610 $aceramic 610 $acharacterization 610 $acharged defects 610 $adielectric relaxation 610 $aelectrical conduction 610 $aelectrocaloric effect 610 $aferroelectric materials 610 $aferroelectric properties 610 $alead-free 610 $aMaxwell relation 610 $an/a 610 $aNBT epitaxial film 610 $aP-E hysteresis loop 610 $apiezoelectric 610 $aPMN-32PT 610 $aPMN-32PT single crystal 610 $aPMN-PT 610 $aRF magnetron sputtering 610 $asegregation 610 $asingle crystals 610 $aultraviolet light 615 7$aResearch & information: general 700 $aDec$b Jan$4edt$01312707 702 $aDec$b Jan$4oth 906 $aBOOK 912 $a9910557533403321 996 $aSynthesis and Characterization of Ferroelectrics$93030938 997 $aUNINA
