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 concept of parallel confocal microscopy with aperture de-correlation has been developed in order to reduce acquisition time and to increase light efficiency over conventional scanning confocal microscopy. It consists in simultaneously observing numerou ...
The concepts of near-field optical microscopy and experimental and theoretical work carried out in Switzerland over the last 10 years are reviewed. After a description of the pioneering experiments of the mid-1980s, we focus on the recent efforts of the th ...
The study of semiconductor interfaces and of solid interfaces in general requires novel instrument capable to investigate the lateral fluctuations of properties on a microscopic scale. We present the first result of a major effort in that framework, whose ...
First experiments of coupling a free electron laser to a scanning near-field optical microscope (SNOM) are presented. To address the question of how important such spectroscopy can be for near-field infrared microscopy, we acquired images of the same regio ...
The fluorescence resonance energy-transfer (FRET) process was studied between donor dye mols. deposited on the sample surface and acceptor dye mols. deposited on the tips of scanning near-field and at. force microscopes. The FRET process was obsd. only whe ...
We report a microscopic study of the Au/5 Angstrom SiNx/GaAs Schottky barrier based on scanning near-field optical microscopy. Photocurrent yield microimages taken at different photon energies reveal non-topographic features. Taking into account their depe ...
Scanning near-field optical microscopy (SNOM) is an optical microscopy whose resolution is not bound to the diffraction limit. It provides chemical information based upon spectral, polarization and/or fluorescence contrast images. Details as small as 20 nm ...
Synchrotron-light-based microscopic interface characterization techniques have been a major factor in the progress towards the understanding control of interface properties and performances. Their role was recently enhanced by the advent of third-generatio ...
We present three-dimensional simulations of the image formation process in near-field optical microscopy, Our calculations take into account the different components of a realistic experiment: an extended metal coated tip, a subwavelength sample and its su ...
We present photoemission spectromicroscopy results on biological specimens. The data, obtained with x-ray secondary (photoelectron) emission microscopy, study individual elements in micrometer-size portions of neuron networks. ...
