Leakage conduction of (Pb, La)(Zr, Ti)O-3 (PLZT) films grown on Pt bottom electrode, with Pt and Pt/SrRuO3 (Pt/SRO) top electrodes is studied. It is found that the conduction behavior of the ferroelectric capacitors strongly varies depending on the degree ...
Poling of calcium and zirconium modified lead titanate pyroelelectric thin films has been studied, Poling temperature and electrical field were optimized to achieve high figure of merits. It was found that thermal activation is important to obtain highly p ...
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 ...
A surprising non-cumulative effect of the degradation mechanism (fatigue) of the switched polarization (P-r(s)), was observed in MOCVD and sol-gel prepared Pb(Zr0.47Ti0.53)O-3 (PZT) ferroelectric thin films capacitors (FECAP) with Pt-electrodes. This effec ...
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 ...
