(100)-oriented stoichiometric LSCO films were deposited on Pt/TiO2/SiO2/Si, TiO2/Pt/TiO2/SiO2/Si and Si substrates with rf magnetron sputtering using a single self fabricated oxide target. Best conductive LSCO film was obtained at 600 degrees C, yielding a ...
To deposit cryolite thin films with a composition close to the correct stoichiometry on a silicon substrate, a Direst Pulsed Laser Deposition (DPLD) set-up and a Crossed Beam Pulsed Laser Deposition (CBPLD) set-up have been used. In the case of CBPLD two t ...
A method for a binder-free manufg. a nanostructured porous film, e.g. for use in solar cells, comprises the steps of: prepg. a suspension of semi-conducting nanometer-sized particles in a volatile suspending agent , depositing the particle suspension on a ...
A review with 20 ref. Ti oxide films were made by reactive DC magnetron sputtering onto elec. conducting glass substrates. The films were dye sensitized with an Ru complex, thereby yielding nanocryst. solar cells. We investigated the microstructure of the ...
Nanocryst. TiO2-based films with a special penniform microstructure were prepd. by reactive d.c. magnetron sputtering followed by dye sensitization. The films were integrated in a solar cell configuration and were able to yield a higher photocurrent than s ...
This paper describes a detailed study of the behavior of the parallel spring stage having four circular flexure hinges of very thin cross-sections manufactured by wire electro-discharge machining. The state of the art recalls the abundant literature publis ...
The texture of sputter deposited PbTiO3 films could be turned from (100)- to (111)-orientation by adding a few nm thick TiO2 layer onto the textured Pt(111) substrate film. AES, XPS, and XPD measurements showed that such TiO2 films were epitaxially ordered ...
The influence of Ta, Ti and TiO2 adhesion layers with Pt bottom electrodes and the deposition temperature of the metallization on the nucleation and growth of sol-gel derived Pb(Zr0.53Ti0.47)O-3 thin films is reported. Several different PZT annealing profi ...
Using the new 'quality parameter', μoτo, the authors were able to show, for the first time, a clear correlation between transport properties of a series of a-Si:H films (grown at various deposition temperatures) and the efficiency of p-i-n cells incorporat ...
The authors present superconducting YBa2C3O7 (YBCO) thin films grown in-situ by three-ion-beam sputtering. Y, Y2O3, Cu, Cu2O, BaF2 and BaCO3 sputter targets have been investigated. The highest quality films were prepared using a BaCo3 target. Auger analysi ...
