Porous Gold Films Fabricated by Wet-Chemistry Processes

Aymeric Pastre, Odile Cristini, Alexandre Boé, Katarzyna Raulin, Bertrand Grimbert, Fernand Chassagneux, Nathalie Rolland, Remy Bernard

Porous gold films presented in this paper are formed by combining gold electroless deposition and polystyrene beads templating methods. This original approach allows the formation of conductive films (2 × 106 (Ω·cm)−1) with tailored and interconnected porosity. The porous gold film was deposited up…

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…

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.…

LEAD-FREE BNT PIEZOELECTRIC THIN FILMS BY SOL-GEL METHOD

Sara Abou Dargham, Freddy Ponchel, M. Soueidan, Antonio Khoury, Jamal Assaad, Denis Remiens, Doumit Zaouk

The objective of this work is to synthesize lead-free piezoelectric thin films by the Sol-Gel method: bismuth sodium titanate (Bi0.5Na0.5TiO3 or BNT). BNT films were annealed with the rapid thermal process (RTP). The film treated at 700°C is dense and well crystallized in the perovskite phase. The…
