The effects of donor (Nb, Ta) and acceptor (Na, Mg, Fe) dopants on the crystallization mechanism of PZT thin films were investigated. The parameters which control microstructure development were found to be different for donors and accepters. Lead stoichio ...
In situ reactively sputter deposited, 300-nm-thick Pb(Zrx,Ti1-x)O3 thin films were investigated as a function of composition, texture, and different electrodes (Pt,RuO2). X-ray diffraction analysis, ferroelectric, dielectric, and piezoelectric measurements ...
The paper discusses different possibilities for controlling piezoelectric properties of ferroelectric materials and devices. The piezoelectric properties engineering can be made on different scales. Tuning of the piezoelectric response by controlling contr ...
The pyroelectric properties of Pb1-xCaxTiO3 (x = 0-0.3) thin films have been greatly improved by including porosity in the microstructure. Control of nucleation and growth by variation of the heating rate was used to process porous, low dielectric constant ...
Mechanisms of polarization switching and fatigue in (Pb, La)(Zr, Ti)O-3 (PLZT) films are studied by comparative analysis of degradation and leakage conduction of PLZT capacitors with Pt, SrRuO3 (SRO), and layered Pt/SRO (80/5 nm) electrodes. It is found th ...
It was recently suggested, basing on the analysis of a wide range of macroscopic experimental results([1-4]), that fatigue in ferroelectric thin film capacitors, particularly in the case of PZT with metallic electrodes (Pt), must be related to the freezing ...
The shape of the grains and the granulometry distribution of the PZT powder are the main factor influencing the densification. In addition, we shown that a higher concentration of PZT powder in the ink with a right rheology of the ink improves the density ...
In this paper the simple accelerometers based on PZT thin films were developed and characterized. The functions of seismic mass and spring are given by a boss loaded cantilever structure. The strain of the cantilever is detected by a Pb(Zr,Ti)O-3 thin film ...
The piezoelectric properties of rhombohedral relaxor-ferroelectric compositions close to morphotropic phase boundary have been studied as a function of temperature. As they exhibit, upon heating, a rhombohedral to tetragonal phase transition the piezoelect ...
The self-polarization effect is investigated in Pb(Zr,Ti)O-3 (PZT) thin films deposited by sol-gel and magnetron sputtering techniques. The effective piezoelectric coefficient of as-grown films, which is proportional to their initial polarization (self-pol ...
