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 electronic ground state of a periodic crystalline solid is usually described in terms of extended Bloch orbitals; localized Wannier functions can alternatively be used. These two representations are connected by families of unitary transformations, car ...
Random defects destroy long-range phase coherence, and inhibit the metal-insulator transition in the charge density wave (CDW) system 1T-TaS2. Photoelectron spectroscopy with high resolution reveals corresponding changes in the electronic structure. Core l ...
Pseudopotential calculations within density-functional theory for a few selected solids (Si, GaAs, and Al) are used to assess the validity of two generalized-gradient approximations (GGA's), the one proposed by Becke and Perdew (BP) and the more recent one ...
We have exploited the resonant enhancement of the Ce 4f cross section around 120 eV to investigate the nature of the 4f states in CePd3 and CeSb. Our results are qualitatively consistent with the predictions of the Anderson Impurity Model. In CePd3 our hig ...
We have exploited angle-resolved photoelectron spectroscopy (ARPES) to study the electronic structure of single crystal samples of high T-c material Bi2Sr2CaCu2O8+delta and of the antiferromagnetic insulator Sr2CuO2Cl2. As one moves away from optimal dopin ...
We exploited angle-resolved photoelectron spectroscopy (ARPES) with high energy resolution to map the band structure of the typical one-dimensional organic conductor TTF-TCNQ. We directly observe dispersing spectral features corresponding to the donor (TTF ...
We review, from a unified point of view, a general class of models of itinerant electrons interacting with classical fields. Applications to the static Holstein, Kondo, and Hubbard models are discussed. The ground state structure of the classical field is ...
Experimental Al KL(23)V and Ni LMM Auger and high-resolution valence band XPS spectra of Al3Ni and AlNi3 alloys are presented and compared to the corresponding spectra of pure metals. The spectra are interpreted in terms of the results of the discrete-vari ...
The bonding of Pd atoms evaporated on a thin layer of silicon intermediate oxidation states has been studied by core level and valence band photoemission spectroscopy. The particular substrate was obtained by controlled exposure of a cleaved Si surface to ...
We developed InGaAsP BRAQWET (barrier, reservoir, and quantum-well electron transfer) structures using numerical modeling to optimize the band structure. The main improvement was achieved by including i,n,i,p-doped layers in the barrier, thus decoupling th ...
