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 authors have demonstrated, by using a simple single YBa2Cu3O7-x target ion beam system that, with a sufficiently low power ion beam, preferential sputtering is avoided and high-quality YBa2Cu3O7-x films are deposited over areas larger than ≈30 cm2 i ...
Fiber optic modulators were fabricated by coating optical fibers with electrode and piezoelectric ZnO layers. The techniques of piezoelectric fiber optic modulator (PFOM) fabrication are presented, and the microstructure and crystallographic texture of the ...
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 ...
Electrodeposition of magnetic multilayers was achieved in the cylindrical pores of a nuclear track-etched polycarbonate membrane. An assembly of wires with an average diameter of 80 nm and a length of 6 μm was obtained. Multilayers in these wires were grow ...
Surface chemical composition and topography of Pt-SnO2 thin films grown by radiofrequency (rf) reactive sputtering on two different Al2O3 substrates (rough and mechanically polished) were investigated by x-ray photoemission spectromicroscopy (XPSM) and ato ...
The microstructure and chemical composition of sputtered thin films are strongly correlated with the deposition conditions. In the present work, we report the investigation of the film composition by electron probe microanalysis and photoemission experimen ...
We present preliminary results for thin films grown with a recently commissioned ion beam codeposition system designed for in situ growth and etching of YBCO films. The apparatus consists of a high-vacuum chamber (10-7 Torr) equipped with four Kaufmann ion ...
Superconducting YBCO thin films have been grown in-situ by three ion beam co-deposition sputtering. Both metal and oxide targets of Cu and Y and BaF2 and BaCO3 targets have been investigated. Film composition was determined by RBS and AES analysis. Films g ...
