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 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 ...

We report here on ferromagnetic/superconductor FM/SC and SC/FM double layers deposited without a buffer layer between FM and SC. Thin films of La0.7Sr0.3MnO3 (LSMO) are used for the FM, and YBa2Cu3O7-x (YBCO) for the SC. Both films can grow crystalline on ...
Integrated optical devices can be fabricated by the deposition of an electrode/piezoelectric/electrode multilayer thin film structure onto optical fibers, The particular structure used in this work is Au/PbTiO3/Pt/Ti, where the PbTiO3 is deposited by DC re ...
It is shown that a strong but diffuse dielectric anomaly, commonly expected only in disordered ferroelectrics, may be inherent in strained and defect-free perovskite ferroelectric thin films. The origin of this unusual anomaly, which was never predicted fo ...
PZT thin films for memory applications are known to lack sufficient resistance versus polarization fatigue when used together with platinum. One possible solution for this problem is to use conductive oxides like La1-xSrxCoO3 (LSCO) as an electrode. In thi ...
There is a need for chemically resistant coatings that protect the exposed surface of microfluidics components. Pinhole free films with low stress and a good uniformity on flat and inclined surfaces are required. In this study, amorphous silicon carbide (S ...
A diol-based sol-gel method was used to prepare UV sensitive precursor solutions in the processing of modified lead titanate ferroelectric thin films. Films were deposited by spin-coating onto platinized Si-based substrates. A preferential orientatio ...
Novel design of an integrated digital refelction-type phase shifter based on a Barium Strontium Titanate thin-film capacitor is presented. Measured characteristics of the phase shifter am compared with the theoretically predicted ones. ...
We use molecular dynamics to analyze the dependence on the impact angle of the distribution of defects originated by the deposition of a Ag/sub 19/ cluster on Pd(100) at initial kinetic energies 0.1, 2, 20 and 95 eV. For increasing energy the cluster under ...
