Thermal conductivity of deca-nanometric patterned Si membranes by multiscale simulations

Hayat Zaoui, Pier Luca Palla, Stefano Giordano, Fabrizio Cleri, Maxime Verdier, David Lacroix, J.F. Robillard, Konstantinos Termentzidis, Évelyne Martin

The hollowing of silicon membranes to form a lattice of cylindrical holes, also called phononic crystal, has been used by several experimental groups willing to fabricate efficient thermoelectric modules. The idea is to reduce the thermal conductivity without impacting the electronic conductivity.…

Compact Waveguide and Guided Beam Pattern Based on the Whispering-Gallery Mode of a Hollow Pillar in a Phononic Crystal Plate

Weitao Yuan, Jinfeng Zhao, Bernard Bonello, Bahram Djafari-Rouhani, Xiaoqing Zhang, Yongdong Pan, Zheng Zhong

We report on the experimental evidence of the guiding of the lowest order antisymmetric Lamb mode (A0) through a compact waveguide consisting of aligned hollow pillars in between a square-latticed array of solid pillars on a thin slab. We analyze both numerically and experimentally the guiding…

A fully flexible circuit implementation of clique-based neural networks in 65-nm CMOS

Benoit Larras, Paul Chollet, Cyril Lahuec, Fabrice Seguin, Matthieu Arzel

Clique-based neural networks implement low- complexity functions working with a reduced connectivity be- tween neurons. Thus, they address very specific applications operating with a very low energy budget. This paper proposes a flexible and iterative neural architecture able to implement multiple…

Surface acoustic waves in one-dimensional piezoelectric-metallic phononic crystal: Effect of a cap layer

M. Alami, E. H. El Boudouti, Bahram Djafari-Rouhani, Y. El Hassouani, Abdelkrim Talbi

We study the propagation of transverse acoustic waves associated with the surface of a semi-infinite superlattice (SL) composed of piezoelectric-metallic layers and capped with a piezoelectric layer. We present closed-form expressions for localized surface waves, the so-called Bleustein-Gulyaev (BG…

Effect of MoS2 layer on the LSPR in periodic nanostructures

Mohamed El Barghouti, Abdellatif Akjouj, Abdellah Mir

Abstract In this work, we propose a new configuration of the localized surface plasmon resonance (LSPR), based on MoS2 hybrid structures for ultrasensitive biosensing applications. The plasmonic resonances are widely used in bimolecular detection and continue to be an active network because of the…

Trapped-mode-induced Fano resonance and acoustical transparency in a one-dimensional solid-fluid phononic crystal

Ilyasse Quotane, El Houssaine El Boudouti, Bahram Djafari-Rouhani

We investigate theoretically and numerically the possibility of existence of Fano and acoustic-induced transparency (AIT) resonances in a simple though realistic one-dimensional acoustic structuremade of solid-fluid layers inserted between two fluids. These resonances are obtained by combining…

Digital complex delta-sigma modulators with highly configurable notches for multi-standard coexistence in wireless transmitters

Razvan-Cristian Marin, Antoine Frappé, Andreas Kaiser

This paper presents a complex delta-sigma modu-lator (CDSM) designed for integration in a digital transmitter chain targeting multi-standard coexistence with nearby receivers. The use of a DSM has the advantage of increased performance in terms of signal-to-noise-ratio in the band of interest.…

Thin-film adhesion characterization by Colored Picosecond Acoustics

Arnaud Devos, P. Emery

This paper presents some applications of a recent technique so-called the Colored Picosecond Acoustics (APiC) to the characterization of complex stacks of thin films. The technique is a unique combination of optics and acoustics that implements an acoustic pulse-echo technique at the nanoscale…
