PZT Thin Film (pzt + thin_film)
Selected AbstractsElectrical Nanoscale Training of Piezoelectric Response Leading to Theoretically Predicted Ferroelastic Domain Contributions in PZT Thin Films,ADVANCED MATERIALS, Issue 16 2008Simon Bühlmann Piezoelectric contributions from mobile 90° domains are locally activated by electrical training of a PZT thin film. The high response state of 160 pm V,1 corresponds well with theoretical predictions. This state relaxed at modest trainings within minutes but was stabilized after extensive training. Our findings indicate that dramatic domain reconfigurations must take place. [source] Control of Crystal Orientation and Piezoelectric Response of Lead Zirconate Titanate Thin Films Near the Morphotropic Phase BoundaryJOURNAL OF THE AMERICAN CERAMIC SOCIETY, Issue 4 2002Ken-ichi Kakimoto PbZr0.53Ti0.47O3 (PZT) thin films with various preferred crystallographic orientations were synthesized on various substrates using pulsed laser deposition techniques. Larger piezoelectric displacement, which involved the bending vibration of the PZT film/substrate, was observed in randomly oriented PZT thin film than that in (100)- and (111)-preferred texture films. This result was discussed by correlation with the number of effective spontaneous polarization axes in the morphotropic phase boundary of the PZT system. Moreover, polarization fatigue was found to lower the electric-field-induced displacement significantly, indicating a large contribution of ferroelectric domain motion to the piezoelectric response of PZT thin films under bipolar drive.
