Chattez avec Graph Search
Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
The authors report on the in-situ growth over large area of high-quality homogeneous YBa2Cu3O7-x films by single target ion beam sputtering. The 123 stoichiometry transfer to the substrates is obtained by using sufficiently low power ion beams and a grazin ...
Spin-coated solid films of the gold-cluster compd. dodeca-(triphenylphosphine), hexa(chloro)pentapentacontagold Au55(PPh3)12Cl6 are irradiated with a focused 20-keV Ga+ focused-ion beam. Writing speeds on the substrate ranged from 50 up to 2000 mm/s. This ...
In situ Fourier transform infrared absorption spectroscopy has been used to study the composition of particles formed and suspended in radio-frequency discharges of silane-oxygen-argon gas mixtures. The silane gas constumption was observed by infrared abso ...

Detailed investigations of the limits of a new negative-tone near-UV resist (IBM SU-8) have been performed. SU-8 is an epoxy-based resist designed specifically for ultrathick, high-aspect-ratio MEMS-type applications. We have demonstrated that with single- ...
The authors have produced YBaCuO thin films by mono-target ion beam sputtering. Post annealing in O2 at 850°C results in superconducting films on (100) SrTiO3 with R=0 at ~60 K. Preliminary results of chemical analysis of the films by X-ray photoelectron s ...
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 ...
