We deposited transparent ferroelectric lead zirconate titanate thin films on fused silica and contacted them via Al-doped zinc oxide (AZO) transparent electrodes with an interdigitated electrode (IDE) design. These layers, together with a TiO2 buffer layer on the fused silica substrate, are highly transparent (>60% in the visible optical range). Fully crystallized Pb(Zr0.52Ti0.48)O3 (PZT) films...

Lead Zirconate ceramics are technically and commercially important piezoelectric materials. It is an antiferroelectric ceramic. The antiferroelectric (AFE) to ferroelectric transition, under the application of a strong electric field, leads to significant energy storage for a dc field. This feature of PbZrO3 makes it a candidate material for energy storage applications. In the present study, th...

The optical properties of lead zirconate titanate (PZT) thin films deposited on ZnO were studied by m-lines spectroscopy. In order to retrieve the refractive index and the thickness of both layers from the m-lines spectra, we develop a numerical algorithm for the case of a two-layer system and show its robustness in the presence of noise. The sensitivity of the algorithm of the two-layer model ...

In the present work, the deposition and characterization of dielectric, piezoelectric, semiconductor and conductor films by RF diode / RF magnetron sputtering process for applications in MEMS fabrication have been reported. Thin films of silicon dioxide, silicon nitride, amorphous silicon, zinc oxide and lanthanum doped lead zirconate titanate (PLZT) were prepared by RF sputtering process and e...

Antiferroelectric lead zirconate is the key ingredient in modern ferroelectric and piezoelectric functional solid solutions. By itself it offers opportunities in new-type non-volatile memory and energy storage applications. A highly useful and scientifically puzzling feature of this material is the competition between the ferro- and antiferroelectric phases due to their energetic proximity, whi...

Corrosion of metal structures is often prevented using cathodic protection systems, that employ sacrificial anodes corrode more preferentially relative to the be protected. In-situ monitoring these during early stages their useful life could offer several insights into deterioration material surrounding infrastructure as well serve warning indicator for preventive maintenance critical infrastru...
