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.
Using angle-resolved photoelectron spectroscopy we investigate the electronic valence band structure of the Si(331)-(12 × 1) surface reconstruction for which we recently proposed a structural model containing silicon pentamers as elementary structural buil ...
The electronic structure of cis-bis(4,4'-dicarboxy-2,2'-bipyridine)bis(isothiocyanato)ruthenium(II) and of its ligand 2,2'-bipyridine-4,4'-dicarboxylic acid was studied with electron spectroscopy. Valence level spectra were studied with respect to photoele ...

Organic semiconductors are promising materials for future electronic and electroluminescence applications. A detailed understanding of organic layers and nano-sized crystals down to single molecules can address fundamental questions of contacting organic s ...
Due to the limiting amount of fossil fuel available and to the continuous growth of the world energy consumption, it becomes important to find alternative energy sources. Hydrogen produced by the photoelectrolysis of water is a perfect candidate as a clean ...
We show that, contrary to intuition and under normal experimental conditions, the band bending at a semiconductor surface or interface does not strongly increase the linewidth of photoemission core-level peaks. The increase is smaller than the magnitude of ...
A study of the formation of In- and Au-GaAs(100) interfaces is reported. The metal overlayers are deposited in ultrahigh vacuum on room-temperature (RT) and low-temperature (LT) (100)GaAs grown by molecular-beam epitaxy, following the evaporation of a prot ...
Some redox-active ionic liquids, organic amorphous solids containing electron-donating moieties, and conductive polymers can efficiently transport positive electrical charges. These hole-conducting media find increasing applications in unconventional solar ...
Presents a synchrotron radiation photoemission study of the upper-valence-band states of four ZrSe3-structure compounds: ZrS3, ZrSe3, ZrTe3 and HfSe3. The sulphide and selenide spectra exhibit a charac ...
We investigated the adsorption properties of methanol and ethanol on Si(111)2 x 1 as a function of temperature in the range 80-300 K by means of synchrotron radiation photoemission of core and valence levels. A physisorbed state is characterized at 80 K, w ...
