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.
In situ electron microscope observations of defects show that the incident high-energy electrons influence the evolution of microstructure of an irradiated material, reducing the number of defects seen in the field of view of the microscope. We investigate ...
In-situ materials tests have the advantage to link visual and sensor based information during a dynamic experiment. In this thesis, a compact indenter-scratch test device has been built at EPFL-LSRO and installed inside a Scanning Electron Microscope (SEM) ...
The controlled tuning of the characteristic dimensions of two-dimensional arrays of block-copolymer reverse micelles deposited on silicon surfaces is demonstrated. The polymer used is polystyrene-block-poly(2-vinylpyridine) (91500-b-105000 g mol–1). Revers ...
The general idea of Nanotechnology is not new – it has been studied since Nobel laureate Richard Feynman outlined the idea in a speech in 1959 – but it's only recently that the progress carried out in the various fields of material, optic, physic and engin ...
This work presents the preliminary results on application of mineral sacrificial layer that is prepared to structure LTCC (low temperature co-fired ceramic). The proposed method suggests utilization of a sacrificial paste, which remains "permanent" during ...
This thesis describes the synthesis of carbon nanotubes (CNTs) by chemical vapor deposition (CVD) and the evaluation of them as tips of atomic force microscope (AFM) probes. Both arc-discharge and CVD grown nanotubes were investigated as AFM tips. Two meth ...
The structural characteristics of CdTe/CdS thin-film heterojunctions are investigated. The studied heterojunctions were obtained by successive thermal evaporation under vacuum onto unheated SnO2 coated glass substrates of CdS and CdTe films, respectively. ...
The aim of this study is to develop coatings on polymer substrates with a combined increase in oxygen barrier performance and toughness, based on SiOx coatings modified with multifunctional organo-silane polymers of controlled polarity and reactivity. As a ...
The electron beam induced current (EBIC) technique was used to characterize a 32 μm thick hydrogenated amorphous silicon n-i-p diode deposited on top of an ASIC, containing several channels of active feedback pre-amplifiers (AFP) with peaking time of 5 ns. ...
In this paper, the fabrication and use of stencils for full-wafer scale shadow mask (stencil) lithography is described. The stencils fabricated via microelectromechanical systems are mechanically stabilized and show clearly reduced stress-induced membrane ...
