Accurate impedance measurements on differently sized samples of lead–zirconate–titanate (PbZr0.53Ti0.47O3, PZT) have been analyzed with a CNLS procedure, resulting in the separation of the ionic and electronic conductivities over a temperature range from f 150 to 630 jC. At 603 jC the electronic conductivity shows approximately a (PO2) 1/4 dependence, while the ionic conductivity remains consta...

Ferroelectric domain patterning with an electron beam is demonstrated. Polarization of lead zirconate titanate thin films is shown to be reoriented in both positive and negative directions using piezoresponse force and scanning surface potential microscopy. Reorientation of the ferroelectric domains is a response to the electric field generated by an imbalance of electron emission and trapping ...

Ferroelectric nanostructures are promising building blocks for advanced electromechanical devices. In this paper, we report a hydrothermal synthesis of PbTiO3 nanoring and nanoring-nanowire hybrid structures. Evolution of the nanoring structure was suggested to be caused by the self-directed assembly of PbTiO3 nanoparticles, where polarization of the ferroelectric nanoparticles might direct the...
