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.
This thesis deals with the development of microfabrication technologies based on photoplastic structuring by lithographic and molding techniques. These technologies, combined with an original releasing method, allow for the simple fabrication of pseudo thr ...
Crystals of hexamethylenetetramine (HMT) with aliphatic dicarboxylic acids in 1:1 molar ratio exhibit different behaviour depending on the number n of carbons in the aliphatic chain. For n=8 and 10, incommensurate phases have been observed, while for n=9, ...
The inexpensive fabrication of high-quality probes for nearfield optical applications is still unsolved although several methods for integrated fabrication have been proposed in the past. A further drawback is the intensity loss of the transmitted light in ...
We have studied the photoluminescence properties of GaN quantum dots with submicrometre lateral resolution by means of near-field scanning optical microscopy. The instrument operated at room temperature and was implemented for near-ultra-violet spectroscop ...
We have investigated the photoluminescence properties of GaN quantum dots with sub-micron lateral resolution by means of Near-Field Scanning Optical Microscopy (SNOM) operating in illumination mode. The analyzed sample consists of several stacked planes of ...
We present a hybrid probe for scanning near-field optical microscopy (SNOM), which consists of a micromachined photoplastic tip with a metallic aperture at the apex that is attached to an optical fiber, thus combining the advantages of optical fiber probes ...
Chalcogenide glass optical fibers were fabricated into functional apertured probes for near field scanning infrared microscopy. Probe fiber tips were chemically etched and aluminum coated for the purpose of simultaneously collecting near field shear force ...
In this review we describe fundamentals of scanning near-field optical microscopy with aperture probes. After the discussion of instrumentation and probe fabrication, aspects of light propagation in metal-coated, tapered optical fibers are considered. This ...
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 ...
The fabrication and application of photoplastic scanning force microscopy (SFM) probes has been demonstrated. Simple molding and replication techniques, inexpensive photoplastic material, reusable molds and several layers per probe make it a very attractiv ...
