Wave propagation in layered piezoelectric rectangular bar : an extended orthogonal polynomial approach

J.G. Yu, C. Zhang, Jean-Etienne Lefebvre

Wave propagation in multilayered piezoelectric structures has received much attention in past forty years. But the research objects of previous research works are only for semi-infinite structures and one-dimensional structures, i.e., structures with a finite dimension in only one direction, such...

Longitudinal and transversal polarization switching in strained ferroelectrics

Laurent Baudry, Igor A. Luk'Yanchuk, A. Razumnaya

Using the multicomponent Landau-Devonshire functional we study the field-induced polarization switching in c-oriented ferroelectric phase of epitaxial perovskite film and found that two different regimes are possible: (i) longitudinal switching with change of the polarization modulus and (ii)...

Modeling light-sound interaction in nanoscale cavities and waveguides

Yan Pennec, Vincent Laude, Nikos Papanikolaou, Bahram Djafari-Rouhani, Mourad Oudich, Said El-Jallal, Jean-Charles Beugnot, José Maria Escalante, Alejandro Martinez

The interaction of light and sound waves at the micro and nanoscale has attracted considerable interest in recent years. The main reason is that this interaction is responsible for a wide variety of intriguing physical phenomena, ranging from the laser-induced cooling of a micromechanical resonator...

Elastic properties of tensile nitrogen-plasma-treated multilayer silicon nitride films

M. Braccini, F. Volpi, Arnaud Devos, G. Raymond, D. Benoit, Pascal Morin

Highly stressed silicon nitride thin films are used in gate first complementary metal oxide semiconductors to improve mobility in the silicon channel. Compressive stresses improve hole mobility in p-type MOS transistors while tensile stresses increase electron mobility in n-type MOS devices. High...

Digital radio frequency signal generation towards ultimate transmitters

Antoine Frappé

This invited paper exposes our latest developments in the field of digital transmitters by focusing on digital and mixed-signal processing blocks, such as delta-sigma modulators, high-speed interpolation filters and digital-to-RF converters. The goal is to demonstrate that radio-frequency signal...

Coherent THz communication at 200 GHz using a frequency comb, UTC-PD and electronic detection

Guillaume Ducournau, Y. Yoshimizu, S. Hisatake, F. Pavanello, Emilien Peytavit, Mohammed Zaknoune, T. Nagatsuma, Jean-Francois Lampin

A coherent terahertz (THz) link at 200 GHz, with a variable data rate up to 11 Gbit/s, featuring a very high sensitivity at the receiver, is investigated. The system uses a quasi-optic unitravelling carrier photodiode (UTC-PD) emitter and an electronic receiver. The coherent link relies on an...

Polyaniline-carbon nanotubes composites - Based patch antenna

Z. Hamouda, J.-L. Wojkiewicz, A.A. Pud, B. Belaabed, S. Bergheul, T. Lasri

This paper presents the simulation and realization of a patch antenna made of composites based on Polyaniline (PANI) and carbon nanotubes (CNT). The antenna is designed to work at the frequency of 4.5 GHz; the dielectric substrates used is Rogers RT/duroid 5870 which has a dielectric permittivity...

Phononic engineering of silicon using "dots on the fly" e-beam lithography and plasma etching

Valeria Lacatena, Maciej Haras, J.F. Robillard, Stéphane Monfray, Thomas Skotnicki, Emmanuel Dubois

Nowadays, the interest in reducing the lattice thermal conductivity (kL), without affecting the electrical one (ke), represents one of the main objectives for researchers in thermoelectricity. In semiconductors, lattice vibrations contribute about 95% to thermal conductivity. Because phonons and...
