HIGH-K THIN FILMS AS DIELECTRIC TRANSDUCERS FOR FLEXURAL M/NEMS RESONATORS

Cécile Fuinel, Khadim Daffé, Adrian Laborde, Olivier Thomas, Laurent Mazenq, Liviu Nicu, Thierry Leichle, Bernard Legrand

We show that a nanometer-thick high-K material can be used as an electromechanical transducer to actuate the flexural mode of micro/nanoresonators. In this study, a 15 nm silicon nitride layer is employed on top of 320 nm thick silicon beams. The devices, smaller by 2 orders of magnitude than in…

Zirconia coating for enhanced thermal stability of gold nanoparticles

A. Pastre, O. Cristini-Robbe, L. Bois, F. Chassagneux, D Branzea, A. Boé, C. Kinowski, K. Raulin, N. Rolland, R. Bernard

This paper describes a rapid, simple and one-step method for the preparation of 2–4 nm diameter zirconia-coated gold nanoparticles at room temperature. These nanoparticles were synthesized by two simultaneous processes: the chemical reduction of tetrachloroauric acid with sodium borohydride and the…

Enhanced thermoelectric power factor of Bi2Sr2Co2Oy thin films by incorporating Au nanoparticles

Nian Fu, Liqing Sun, S. Liang, El Hadj Dogheche, Ahmed Addad, Shufang Wang

c-Axis oriented Bi2Sr2Co2Oy thin films imbedded with Au nanoparticles were prepared by pulsed laser ablation a ceramic Bi2Sr2Co2Oy target with a small piece of Au foil overlapped. It was found that the incorporation of Au nanoparticles, about 5–15 nm in diameter, did not disrupt the c-axis…

Investigation of the performance of HEMT based NO, NO2 and NH3 exhaust Gas Sensors for Automotive Antipollution Systems

Yacine Halfaya, Chris Bishop, Ali Soltani, Sundaram Suresh, Vincent Aubry, Paul L. Voss, Jean-Paul Salvestrini, Abdallah Ougazzaden

We report improved sensitivity to NO, NO2 and NH3 gas with specially-designed AlGaN/GaN high electron mobility transistors (HEMT) that are suitable for operation in the harsh environment of diesel exhaust systems. The gate of the HEMT device is functionalized using a Pt catalyst for gas detection.…

Millimeter-wave six-port IQ demodulator in 65 nm SOI CMOS technology

Kamel Haddadi, Christophe Loyez

This work describes a 65 nm SOI CMOS passive mixer architecture consisting of a n-MOS cold-FET and coplanar waveguide (CPW) transmission line matching networks for six-port IQ demodulation of millimeter-wave signals. The circuit architecture avoids the use of coupler in front of the detection…

Delta-sigma based digital transmitters with low-complexity embedded-FIR digital to RF mixing

Razvan-Cristian Marin, Antoine Frappé, Andreas Kaiser

The focus of this contribution is to review delta-sigma based all-digital transmitters and to discuss issues related to large out-of-band quantization noise and possible coexistence problems. Low-complexity embedded-FIR filters are very interesting to relax the filtering constraints while keeping…
