A substrate with transparent electrodes is formed from a transparent material on which is deposited a film of a transparent conducting material with a thickness e 1and a refractive index n 1. A substrate with transparent electrodes is formed from a transpa ...
A thin aqueous film prepared by layer-by-layer assembly of oppositely charged polypeptides on 4-aminobenzoic acid modified porous reticulated vitreous carbon (RVC) electrodes was used with the aim of forming a 3D-ITIES. The film containing a redox mediator ...
We have deposited a Permalloy film on top of a microstripline structure. The ferromagnetic properties of the Permalloy film are analyzed by means of the magneto-optical Kerr effect. We measure the effect of local magnetic fields generated by constant and p ...
Nanoporous ZnO electrodes, dye-sensitized with a ruthenium bipyridyl complex, were used as photoanodes in photoelectrochem. solar cells. By improving the interfacial contact between dyes and ZnO particles in the film, overall solar-to-elec. energy conversi ...
There has been an argument on carbon nanotube (CNT) based gas detectors with a field-effect transistor (FET) geometry: do the response signals result from charge transfer between adsorbed gas molecules and the CNT channel and/or from the gas species induce ...
We report a novel mode of quasi-static oscillatory crack propagation when a cutting tip of moderately large width is driven through a thin brittle polymer film. Experiments show that the amplitude and wavelength of the oscillatory crack paths scale linearl ...
Deposition of thin films via hydrothermal method has various advantages: low deposition temperature, high purity, deposition on a three-dimensional structure, and a large thickness. Although an epitaxial lead zirconate titanate (PZT) thin-film deposition h ...
The results of structural and electrical characterizations of SrTiO3 thin films deposited onto MgO and LaAlO3 substrates by pulsed laser deposition technique are presented. The influence of substrate and annealing procedure on the crystalline structure and ...
Selective dissolution of titanium through a laser patterned oxide film has been achieved in a 3M sulfuric acid-methanol electrolyte. The 250 nm thick oxide film was formed anodically on a flat titanium surface in 0.5 M sulfuric acid. The patterning of the ...
We demonstrate a diffraction geometry which provides strong sensitivity to the microstructure of thin films. While a coherent beam of X-rays is being reflected from the surface of the sample, measurements were made of the scattering of the exit beam below ...
