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.
We describe a new pulsed laser deposition (PLD) system that is linked to an angle-resolved photoemission (ARPES) chamber at the Synchrotron Radiation Center (SRC) in Wisconsin, USA. We also discuss our first results on epitaxially grown YBa2Cu3O7-δ (YBCO) ...
We studied the deposition of Au, In, Ag, and Al overlayers onto clean-cleaved GaTe(001) surfaces at room temperature by x-ray photoelectron spectroscopy. Gold and In overlayers did not produce evidence of chemical reactions, and neither with cation nor ani ...
Aluminum oxidation states in stoichiometric or substoichiometric configuration are studied by core level photoemission spectroscopy on different substrates (SiO2, graphite). They are compared with recent results reported for the interface Si-Al-n+O. Three ...
We demonstrate the possibility of using x-ray photoemission spectroscopy (XPS) to distinguish between the chemical properties of the neuron membrane and of the cytoplasm in brain cells. This was possible by analysing cells de-capped by using a newly develo ...
We report the formation of silicon oxide thin films at room temperature obtained by Ar+ ion bombardment of Si(100) wafers in partial oxygen atmosphere. Samples have been prepared at several ion beam energies (0 less than or equal to E(b) less than or equal ...
The evolution of the argon metastable states density has been studied by absorption spectroscopy in power-modulated plasmas of argon and a mixture of 4% silane in argon. A small concentration of silane suppresses the argon metastable states density by mole ...
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 ...
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 ...
High-resolution core and valence band photoemission as well as photoinduced Auger spectra of metallic Sn, polycrystalline SnO and SnO2 ((110) natural single-crystal cassiterite and polycrystalline) samples were measured in order to give information on loca ...
