Wafer-scale integration of piezoelectric actuation capabilities in nanoelectromechanical systems resonators [PDF]

, 2015
In this work, we demonstrate the integration of piezoelectric actuation means on arrays of nanocantilevers at the wafer scale. We use lead titanate zirconate (PZT) as piezoelectric material mainly because of its excellent actuation properties even when ...

Defect enhanced optic and electro-optic properties of lead zirconate titanate thin films

AIP Advances, 2011
Pb(Zr1-xTix)O3 (PZT) thin films near phase morphotropic phase boundary were deposited on (Pb0.86La0.14)TiO3-coated glass by radio frequency sputtering. A retrieved analysis shows that the lattice parameters of the as-grown PZT thin films were similar to ...

Thin lead zirconate titanate films

, 2006
The subject of study was the growth and nucleation of sol-gel deposited lead zirconate titanate (PZT) films of composition Pb(Zr0_52,Ti0_4g)O3 (PZT52/48). This particular composition is on a phase boundary between titanium-rich tetragonally structured PZT and the zirconium-rich rhombohedral phase.
