    We investigated the effects of compensating charges (at the inclusion-matrix interface) on the piezoelectric properties of ferroelectric 0-3 composites. Our previously developed model [C. K. Wong, Y. M. Poon, and F. G. Shin, J. Appl. Phys. 90, 4690 (2001)] has been extended to include the...

    BiFeO3/Pb(Zr0.5,Ti0.5)O3 (BFO/PZT) multilayer films have been grown on platinum-coated silicon substrate by chemical solution deposition. The remnant polarization is about 12 μC/cm2, which is much bigger than most of pure BFO thin films. P-E measurement shows that there are more obstacles...

    We have demonstrated both experimentally and theoretically that a tin-modified and niobium-modified lead zirconate titanate (Pb(Sn,Zr,Ti)O3) ferroelectric generator system can function as a micro-power supplying source for integrated circuit (IC) chip of separate nonelectric impulse input shock...
