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.
PLZT 4/65/35 thin films were prepared by the acetic acid based sol-gel route. The choice of lanthanum precursor, i.e., acetate or nitrate, influences the functional group content of formamide modified sols and the microstructure of the thin films. The lant ...
The Photocatalytic film of semiconducting iron oxide (Fe2O3), contains an n-dopant, or a mixture of n-dopants, or a p-dopant or a mixture of p-dopants. Electrode consists of a substrate, with one ore more films or photocatalytic arrangements of film of sem ...

Fabrication of high-density ferroelectric memories requires the growth of the ferroelectric material on the drain contact metal. In standard 0.5 mum technology, tungsten plugs are applied to connect the drain contacts to the first metallization level. In t ...
The dynamics of electron-transfer processes between bis(tetrabutylammonium) cis-bis(thiocyanato)bis(2,2'-bipiridine-4,4'-dicarboxylato)ruthenium(II) (called N719) and nanostructured ZnO films were studied by femtosecond and nanosecond spectroscopy. The inc ...
Thin films consisting of nanorods of hematite (α-Fe2O3) with controlled orientation onto transparent conductive glass substrates have been tested as photoelectrochem. cells. These films allow a more efficient transport and collection of photogenerated elec ...
Dye-sensitized nanocryst. TiO2 solar cells are currently under development. Since these cells contain an electrolyte soln. we reviewed the health and safety aspects in view of indoor applications, where personal contact cannot be excluded. Only small amts. ...
We show that a combination of a dye and a nanostructured NiO thin film on a conducting substrate can form a dye-sensitized photocathode that can be an active part in a tandem dye-sensitized solar cell (TDSC). To exptl. demonstrate a dye-sensitized nanostru ...
Polycrystalline aluminum nitride thin films were deposited onto platinum, aluminum, and titanium electrodes by reactive magnetron sputtering in the pulsed direct current mode. The films exhibited all a columnar microstructure and a c-axis texture. The buil ...
The invention provides a device for obtaining an improved efficiency in a photovoltaic, nanostructured, dye sensitized cell structure, comprising a photoactive working electrode, a counter electrode and an electrolyte arranged there-between. The cell struc ...
A limiting factor at high light intensities in dye-sensitized mesoscopic thin film solar cells seem to be the transport of charge through the electrolyte. To get valid parameters to feed into an over all model for a solar cell based on mesoscopic thin film ...
