The influence of ultraviolet (UV) illumination on piezoelectric properties is investigated in lead zirconate titanate (PZT) thin films. It is found that the poling procedure is more effective when the film is exposed to a broadband UV light in the presence ...
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 ...
We present an experimental study of the current induced destruction of superconductivity in films of type-1 superconductors. The most interesting aspect of these experiments is the possibility to observe and investigate different mechanisms of the supercon ...
We used the novel experimental technique of photoemission spectromicroscopy to investigate the active area of SnO(x) thin films for gas sensors, deposited by dc sputtering. First, we analyzed the degree of oxidation and the homogeneity of as-deposited film ...
Physisorbed and covalently bound Langmuir-Blodgett (LB) monolayers of sulfur-bearing lipids on mica and on gold substrates, resp., have been studied. Scanning force microscopy, in topog. and friction modes as well as in contact and non-contact modes have b ...
Photoelectrochem. properties of nanostructured ZnO thin film electrodes have been investigated in the UV and visible regions. For films consisting of 15 nm large undoped crystallites a max. monochromatic current conversion efficiency of 58% was obtained in ...
Pb(Zr,Ti)03 thin films with compositions close to the morphotropic phase boundary deposited onto electroded Si substrates have potential for use in ferroelectric memories, sensors and micromechanical devices. The microstructures of such films prepared by i ...
The aim of this work was to investigate the degradation of the anti-adhesive properties of protective PTFE films during the hot embossing of thermoplasts, and to identify possible failure causes which reduce the lifetime of these films. A comparative XPS s ...
Direct writing of metal features narrower than 100 nm is accomplished by scanning a focused ion beam over a substrate covered with a thin solid metalorg. film. A metalorg. cluster coordination compd. [Ir4(CO)11Br] [N(C2H5)4] is spun on an oxidized Si wafer ...
The microstructure and preferred orientations of rapid thermally annealed Pb(Zr0.53, Ti0.47)O3 films, deposited on Pt/Ti/SiO2/Si electrode/substrates by solution-gel spinning, have been investigated using analytical and high-resolution electron microscopy ...
