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 ...
The main purpose of this thesis is to explore a new concept of SNOM probes. In order to produce more reliable and reproducible tips, we propose to graft a single gold particle of 60 nm diameter onto the aperture of a SNOM probe. The expected advantage of s ...
Single crystals of layered semiconductors such as WS2 and MoS2 have already proven their efficiency as active elements in photovoltaic cells. Due to their high optical absorption coefficient in the visible range, these materials could be used in the form o ...
A new method for measuring local interfacial impedance properties with high lateral resolution was developed by combination of electrochemical impedance spectroscopy (EIS) with scanning electrochemical microscopy (SECM). Alternating current scanning electr ...
Combining the subwavelength resolution of near-field interactions with the optical contrast mechanisms of classical optical microscopy makes scanning near-field optical microscopy an interesting technique for many applications. In spite of more than ten ye ...
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 ...
Several approaches are described with the aim of producing near-field optical probes with improved properties. Focused ion beam milling allows the fabrication of small apertures in a controlled fashion, resulting in probes with excellent polarization prope ...
Fluorescence resonance energy transfer (FRET) was obsd. between donor dye mols. deposited onto the sample surface and acceptor dye mols. deposited onto the scanning near-field optical microscope (SNOM) or at. force microscope tip. FRET was obsd. only when ...
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, ...
We performed lateral force microscopy on thiolipid Langmuir-Blodgett (LB) films physisorbed on mica substrates with a silicon tip of an at. force microscope. The structure of condensed domains, reflecting their sym. morphol., was obsd. The lateral (frictio ...
