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.
Electrode stability, interdiffusion, phase purity and deviation from stoichiometry at the PZT-electrode interface are key issues in PZT thin film integration. This article highlights the use of transmission electron imaging combined with energy dispersive ...
We have evaluated the structure of high-reflectivity InP/InGaAsP distributed Bragg reflectors grown by chemical-beam epitaxy at a growth rate of 3 mu m/h. Transmission electron microscopy combined with electron energy loss spectroscopy indicate lateral flu ...
Discommensurations (DC) and domains in incommensurate charge density wave (CDW) states of the quasi-two-dimensional (PO2)4(WO3)2m (m = 12) bronze have been observed directly by dark-field transmission electron microscopy with use of the CDW satellite refl ...
We have developed an ultra-stable low temperature scanning tunneling microscope (LTSTM) for application in atomic scale spectroscopy and atom manipulation experiments. The design is based on the Besocke type microscope allowing the installation of the LTST ...
Batch equilibrations were performed to investigate the ability of hydroxyapatite (Ca5(PO4)3OH) to chemically immobilize U in two contaminated sediment samples having different organic carbon contents (123 and 49 g kg-1, respectively). Apatite additions low ...
An energy filter receiving an electronic beam oriented along an optical axis. The filter includes a deflecting system which deviates in a dispersion plane not including the optical axis the received beam and a dispersing system which guides the beam sent b ...
Aerolysin is a channel-forming toxin that must oligomerize in order to become insertion-competent. Modeling based on the crystal structure of the proaerolysin dimer and electron microscopic images of the oligomer indicated that a loop in domain 3 must move ...
The influence of neutron irradiation on microstructural evolution and mechanical properties of mono- and polycrystalline molybdenum and its alloys has been investigated. Tensile specimens and 3 mm diameter discs of monocrystals of pure molybdenum and Mo-5% ...
The cathodoluminescence mode of the scanning electron microscope is used for the first time to investigate the lateral dependence of the electron-hole pair generation by the electron beam of the scanning electron microscope m semiconducting material. A mul ...
Space-charge effects (so-called negative-mass instability) as the reason for electron energy spread arising in the region of the electron drift between the cathode and the cavity of a gyrotron are discussed. Theoretical calculations are compared with resul ...
