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.
Using Grazing-incidence small-angle scattering (GISAXS) technique we investigated the surface morphology of polymer films spin-coated on different silicon substrates. As substrates we used either technologically smooth silicon wafers or the same silicon wa ...
Using surface micromachining technology, we fabricated nanofluidic devices with channels down to 10̂nm deep, 200̂nm wide and up to 8̂cm long. We demonstrated that different materials, such as silicon nitride, polysilicon and silicon dioxide, combined with ...
Novel approaches for the development of integrated molecular analysis tools have been tested. A label-free method for molecular detection and characterization based on UV absorbance have been applied and two technologies of silicon photodetectors arrays ha ...
We address the rate of O-2 diffusion through the oxide layer at Si-SiO2 interfaces using an atomic-scale approach. In particular, we investigate the combined effect of a percolative diffusion mechanism and of a dense oxide layer located close to the silico ...
This paper presents the experimental characterization of two-terminal microfabricated capacitors for microarrays with an electrical sensing of label-free deoxyribonucleic acid (DNA). So far, such a concept has been demonstrated only in experimental setups ...
We present a lamellar grating interferometer realized with microelectromechanical system technology. It is used as a time-scanning Fourier-transform spectrometer. The motion is carried out by an electrostatic comb drive actuator fabricated by silicon micro ...
A device includes a silicon substrate provided with a coating including at least one stacking constituted by a plane of GaN or GaInN quantum dots emitting visible light at room temperature in a respective layer of AIN or GaN. The method of making the devic ...
Silicon dioxide (SiO2) films grown on silicon monocrystal (Si) substrates form the gate oxides in current Si-based microelectronics devices. The understanding at the atomic scale of both the silicon oxidation process and the properties of the Si(100)-SiO2 ...
A micro-hotplate device, useful in catalytic high-temperature chemical sensors, micro-chemical reactors and as infra-red source, in particular at temperatures above 600 DEG C, comprises a thin film resistive heater (1) made of a refractory metal silicide s ...
Stencil lithography is an innovative method for patterning that has a great flexibility from many points of view. It is based on shadow mask evaporation using thin silicon nitride membranes that allow the patterning of sub-100 nm features up to 100 μm in a ...
