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 structural changes due to formation of electronic bubbles in solid D2 are studied by fluorescence, fluorescence-excitation, and fluorescence-depletion spectroscopy of the lowest Rydberg state, A 2S+(3ss), of the NO impurity. The A X band is strongly bl ...
We have modeled the decomposition of nonstoichiometric amorphous SiOx upon annealing into silicon and stoichiometric silica, using a new method based on mapping Metropolis Monte Carlo simulations onto rate equations. The concentrations of all oxidation sta ...
Equilibrium phase diagrams in composition-conversion space have been calculated for stoichiometric blends of an epoxy resin with a diamine hardener and dendritic hyperbranched polymers, to which various numbers of epoxy groups have been grafted. An attempt ...
Extended X-ray absorption fine structure (EXAFS) above the In K-edge of luminescent InGaN heterostructures provides a unique probe of local structure on an atomic length scale. Through a process of fitting the experimental spectrum, we can refine a model o ...
Characteristics of hydrogels formed by assocn. of hydrophobically-modified polyethylene glycol (PEG) with fluoroalkyl (Rf) end-groups can be controlled by modulating their mol. structures. Polymers with relatively long PEG chains (e.g., 20 kg/mol PEG with ...
Thick GaN layers grown by HVPE on different starting layers were examined. The resulting layers were found to be homogeneous with good crystalline and surface quality over the whole 2-inch wafer, strongly depending on the starting layers and gas phase comp ...
The ground states of the one-dimensional Falicov-Kimball model are investigated in the small-coupling limit, using nearly degenerate perturbation theory. For rational electron and ion densities, respectively, equal to p/q, pi/q, with p relatively prime to ...
The piezoelectric properties of the bismuth titanate niobate Bi7Ti4NbO21 have been studied. The two phase transitions at 677 degrees and 856 degrees C are analyzed based on the measured piezoelectric properties. It is shown that the Bi7Ti4NbO21 compound is ...
The ultrafast dynamics are reported of bubble formation following excitation of the A 2S+ 3ss(v = 0) Rydberg state of NO trapped in Ar matrixes. The study is carried out by a fs pump-probe technique. The detected signal is the depletion of Rydberg fluoresc ...
The simplest statistical-mechanical model of crystalline formation (or alloy formation) that includes electronic degrees of freedom is solved exactly in the limit of large spatial dimensions and infinite interaction strength. The solutions contain both sec ...
