Water Exclusion at the Nanometer Scale Provides Long-Term Passivation of Silicon (111) Grafted with Alkyl Monolayers

P. Gorostiza, C. Henry de Villeneuve, Q. Sun, F. Sanz, X. Wallart, R. Boukherroub, P. Allongue

This work is a quantitative study of the conditions required for a long-term passivation of the interface silicon−alkyl monolayers prepared by thermal hydrosilyation of neat 1-alkenes on well-defined H−Si(111) surfaces. We present electrochemical capacitance measurements (C−U) in combination with…

Preparation and Characterization of Thin Films of SiO_x on gold substrates for surface plasmon resonance studies

Sabine Szunerits, Rabah Boukherroub

We report here on the fabrication and characterization of stable thin films of amorphous silica (SiO_x) deposited on glass slides coated with a 5 nm adhesion layer of titanium and 50 nm of gold, using the plasma-enhanced chemical vapor deposition (PECVD) technique. The…

A 310°/3.6dB K-band phaseshifter using paraelectric BST thin films

Gabriel Vélu, Karine Blary, Ludovic Burgnies, Jean-Claude Carru, Elisabet Delos, Aurélien Marteau, Didier Lippens

Ferro- and para-electric BaSrTiO/sub 3/ (/spl epsiv//sub r//spl sim/350 and tg/spl delta//spl sim/5/spl times/10/sup -2/ at 0V) thin films were deposited by low-cost sol-gel techniques. Subsequently, the films were used for fabricating coplanar waveguide phaseshifters using tunable finger-shaped…

Charge-injection mechanisms in semiconductor nanoparticles analyzed from force microscopy experiments

Sophie Barbet, Thierry Melin, Heinrich Diesinger, D. Deresmes, Didier Stiévenard

Charge-injection and electric force microscopy experiments are performed in silicon nanoparticles deposited on a doped silicon substrate. We address in this paper the issue of the nanoparticle charging mechanisms. The nanoparticle charging is shown to occur in a regime of permanent current flow…

Generation and coherent detection of terahertz radiation by photomixing : dielectric media characterization

Sophie Matton, Gaël Mouret, Robin Bocquet, Francis Hindle, D. Bigourd, D. Lippens, Jean-Francois Lampin

New results from a far infrared coherent detection scheme are presented. Photomixing has been used for homodyne detection to measure absorption and dispersion of dielectric media. The abnormal dispersion near a rotational transition of carbonyl sulfide has been examined.

Design techniques for very high speed digital delta-sigma modulators aimed at all-digital RE transmitters

Antoine Frappé, A. Flament, Andreas Kaiser, Bruno Stefanelli, A. Cathelin, R. Daouphars

This paper presents a very high-speed delta-sigma modulator for achieving digital generation of radio-frequency signals. About 68 dB of ACLR (adjacent channel leakage ratio) is obtained on the 7.8 GS/s output of the delta-sigma modulator for WCDMA standard. This is achieved by using original…
