Relaxor Pb(Mg1/3Nb2/3)O3(PMN) and its solid solutions with ferroelectric PbTiO3 (PT) are of considerable interest from both the applications and the scientific point of view. In the past, many attempts were made to prepare and study the properties of these ...
The invention relates to an effusing source for film deposition made of a reservoir comprising one hole characterized by the fact that the hole diameter is less than one order of magnitude than the mean free path of the molecules determined by the pressure ...

Highly textured PZT(111), PZT(001/100) and random PZT films have been grown on Pt and RuO2 bottom electrodes by means of an in-situ, multimagnetron reactive sputtering process with three metal targets (Pb, Zr, Ti). The orientation was varied with the botto ...
The effect of 1 MeV ion implantation on leakage conduction, dielectric and ferroelectric properties of the Pt/Pb(ZrxTi1-x)(2)O-3/Pt capacitors is studied for a wide range of implantation doses (10(10)-10(16) cm(-2)). It is shown that the implantation of Pt ...
Dielectric properties of perovskites are studied both to gain insight into fundamental aspects of the freezing of polar disorder, and to investigate their technological potential. The dynamics of freezing of polar disorder is investigated in single crystal ...
A combined PVD/PECVD process for the vacuum deposition of titaniumcontainingamorphoushydrogenatedcarbonfilms is described. Elemental compositions of the deposited films have been determined by in situ core level photoelectron spectroscopy (XPS). The long-t ...
The in-situ growth of PbZrxTi1-xO3 (PZT) and PbTiO3 (PT) thin films by reactive sputter deposition has been investigated for applications with silicon substrates. In-situ deposition from three simultaneously operating magnetron sources was applied. At the ...
The effect of near-by-electrode charge injection on switching of a thin film ferroelectric capacitor is theoretically analyzed. We develop a model of switching affected by charge injection through a surface dielectric layer to calculate the coercive field ...
