1-3 Piezocomposites Based on Super-Cell Structuring for Transducer Applications

Rémi Rouffaud, Franck Levassort, Marc Lethiecq, Mai Pham Thi, Anne-Christine Hladky, Claire Bantignies

—In ultrasound transducers, the most popular fabrication method for 1-3 piezocomposites is the « dice and fill » method where lateral periodicity p is introduced and leads to the occurrence of lateral modes. These spurious modes can drastically damage the performance of the device if they appear...

Tunable Bragg band gaps in piezocomposite phononic crystals

Charles Croënne, Marie-Fraise Ponge, Anne-Christine Hladky, Mai Pham Thi, Franck Levassort, Lionel Haumesser, Jean-Charles Le Bunetel

Phononic Crystals made of piezoelectric composites with 1-3 connectivity are theoretically and experimentally studied. They present Bragg band gaps that depend on the periodic electrical boundary conditions. These structures have improved properties compared to bulk piezoelectric devices....

Polymer thin film deposition using atmospheric pressure single plasma jet or plasma jet array from a Plasma Gun device

Céline Vivien, Eric Robert, Jean-Michel Pouvesle

Plasma Enhanced Chemical Vapour Deposition (PECVD) processes have been used for decades for surface processing in a wide range of industrial applications like semiconductor films, low-k films, barrier diffusion. Thin film deposition is especially of high interest for biomedical applications for the...

Thermoelectric energy conversion: How good can silicon be?

Maciej Haras, Valeria Lacatena, François Morini, J.F. Robillard, Stephane Monfray, Thomas Skotnicki, Emmanuel Dubois

Lack of materials which are thermoelectrically efficient and economically attractive is a challenge in thermoelectricity. Silicon could be a good thermoelectric material offering CMOS compatibility, harmlessness and cost reduction but it features a too high thermal conductivity. High harvested...

Monte Carlo model for the analysis and development of III-V Tunnel-FETs and Impact Ionization-MOSFETs

V. Talbo, J. Mateos, T González, Y. Lechaux, Nicolas Wichmann, S. Bollaert, V Vasallo

Impact-ionization metal-oxide-semiconductor FETs (I-MOSFETs) are in competition with tunnel FETs (TFETs) in order to achieve the best behaviour for low power logic circuits. Concretely, III-V I-MOSFETs are being explored as promising devices due to the proper reliability, since the impact...

Improvement of interfacial and electrical properties of Al2O 3 / n-Ga0.47 In0.53 As for III-V impact ionization MOSFETs

Y. Lechaux, A. Fadjie, S. Bollaert, V. Talbo, J. Mateos, T González, V Vasallo, Nicolas Wichmann

In this work, Metal - Oxide - Semiconductor Capacitors (MOSCaps) based on Al2O3/ n-Ga0.47In0.53As interface have been studied. In order to have high MOSFETs performance, it is necessary to improve the semiconductor - oxide interface quality. It is observed that the (NH4)2S passivation shows lower...

Experimental analysis of UWB signal performance in a constrained environment for railway application

Ouafae Cohin, Sara Iben Jellal, Fouzia Boukour, S. Baranowski

In the railway application, in order to establish the communication between wagons, some technologies are proposed such as the ZigBee and HTN (Hybrid Networking Technology). However, these techniques have some limitations such as: the low data rate, non-secured transmission and interferences. The...
