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.
In this thesis I report on the unique novel possibilities offered by combining pulsed laser deposition (PLD) film growth of high temperature superconductors with angle integrated and angle resolved photoemission spectroscopy (PES and ARPES). The originalit ...
All strongly correlated materials exhibit fascinating physical properties, like Mott insulator transitions, high temperature superconductivity, Kondo and heavy fermion behavior, colossal magnetoresistance, etc. These properties make them attractive for dev ...
The discovery of high temperature superconductivity in the cuprates in 1986 has boosted the research in strongly correlated materials. One strong motivation was and stays the understanding the high-Tc phenomenon with the hope that one can ultimately engine ...
Detailed data on the momentum-resolved temperature dependence of the superconducting gap of Bi2Sr2CaCu2O8+x are presented, complemented by similar data on the intensity of the photoemission superconducting condensate spectral area. The gap anisotropy betwe ...
The microscopic damage mechanisms at cryogenic temperature of an extra low interstitial Ti-6Al-4V obtained by powder metallurgy (PM) are investigated. Through SEM observations and EBSD mapping, it is attempted to identify the microstructural features that ...
We report on the temperature stability of N@C-60 peapods using electron spin resonance. The atomic nitrogen escapes at higher temperatures in the peapod than in the crystalline form. We also report on the synthesis of novel magnetic fullerene peapod, a ful ...
We present specific-heat data on the type-II superconductors V3Si, LuNi2B2C and NbSe2 which were acquired with a low-temperature thermal analysis (DTA) technique. We compare our data with available literature data on these superconductors. In the first par ...
One view of the high-transition-temperature (high-T-c) copper oxide superconductors is that they are conventional superconductors where the pairing occurs between weakly interacting quasi-particles (corresponding to the electrons in ordinary metals), altho ...
The search for the coexistence between superconductivity and other collective electronic states in many instances promoted the discovery of novel states of matter. The manner in which the different types of electronic order combine remains an ongoing puzzl ...
Despite a large amount of data and numerous theoretical proposals, the microscopic mechanism of ransport in thick-film resistors remains unclear. However, recent low-temperature measurements point toward a possible variable-range-hopping mechanism of trans ...
