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 ...
Systems comprising a dense TiO2 film electrode, a ruthenium polypyridine dye and a PEDOT-PSS (poly(3,4-ethylenedioxythiophene)-poly(4-styrenesulfonate)) film were prepd. The heterojunctions have photovoltaic properties, with the dye absorbing the light, th ...
In this paper, a complete system is presented which mimics a QWERTY keyboard on an arbitrary surface. The system consists of a pattern projector and a true-3D range camera for detecting the typing events. We exploit depth information acquired with the 3D r ...
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 ...
Dans le contexte actuel, les questions relatives à l'utilisation de l'énergie sont de plus en plus prises en considération. Dans ce cadre, certains fournisseurs français sont tenus de faire diminuer la consommation de leur clients. Il est donc important de ...
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 ...
During nanoindentation measurements of thin films the formation of cracks within the film as well as of pile-up or sink-in around the indent are known to affect significantly the precision of hardness and Young's modulus values. The crack pattern in brittl ...
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 ...
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 ...
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 ...
