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...

Lamb wave acousto-optic modulator in ZnO/MgO multiple quantum wells and comparison with classical modulator

Tadeusz Gryba, Jean-Etienne Lefebvre, L. Elmaimouni, F.E. Ratolojanahary

An analysis of a ZnO/MgO multiple quantum well (MQW) acousto-optic modulator with Lamb waves is performed. With the MQW thickness in the range of 0.2 times the Lamb wavelength, the only observed Lamb modes are the lowest-order symmetric S0 and antisymmetric A0 modes. These modes induce strain and...

Investigation of micro and nano structured materials for acoustic band gaps engineering in electro-acoustic devices, Etude et développement de matériaux micro/nano structurés pour l’ingénierie des bandes interdites dans les dispositifs électro-acoustiques à ondes de surface

Yu Du

This work concerns the study of micro/nano structured materials for the engineering of band structures in the field of elastic waves. We were interested in particular to the integration of these materials in electro-acoustic devices and the study of the interaction with the surface acoustic waves...., Ce travail porte sur l’étude de matériaux micro/nano structurés permettant l’ingénierie des structures de bande dans le domaine des ondes élastiques.

Lead-Free α-La2WO6 Ferroelectric Thin Films

Thomas Carlier, Marie-Hélène Chambrier, Anthony Ferri, Sonia Estradé, Jean-François Blach, Gemma Martín, Belkacem Meziane, Francesca Peiró, Pascal Roussel, Freddy Ponchel, Denis Remiens, Albert Cornet, Rachel Desfeux

(001)-Epitaxial La2WO6 (LWO) thin films are grown by pulsed laser deposition on (001)-oriented SrTiO3 (STO) substrates. The α-phase (high-temperature phase in bulk) is successfully stabilized with an orthorhombic structure (a = 16.585(1) Å, b = 5.717(2) Å, c = 8.865(5) Å). X-ray-diffraction pole-...
