Development of broadband high-frequency piezoelectric micromachined ultrasonic transducer array

Xu-Bo Wang, Le-Ming He, You-Cao Ma, Wen-Juan Liu, Wei-Jiang Xu, Jun-Yan Ren, Antoine Riaud, Jia Zhou

Piezoelectric micromachined ultrasonic transducers (PMUT) are promising elements to fabricate a two-dimensional (2D) array with a pitch small enough (approximately half wavelength) to form and receive arbitrary acoustic beams for medical imaging. However, PMUT arrays have so far failed to combine...

Monte Carlo analysis of the influence of surface charges on GaN asymmetric nanochannels: bias and temperature dependence

E. Pérez-Martín, I. Íñiguez-De-La-Torre, Christophe Gaquière, T. González, J. Mateos

In this paper, the occupancy of sidewall surface states having a clear signature in the performance of AlGaN/GaN-based self-switching diodes (SSDs) is analyzed using a semi-classical Monte Carlo (MC) simulator in a wide temperature ( T) range, from 100 to 300 K. Experimental I- V curves show an...

An effective thermal conductivity model for architected phase change material enhancer: theoretical and experimental investigations

Romain Hubert, Olivier Bou Matar, Jerome Foncin, Philippe Coquet, Dunlin Tan, Hongling Li, Edwin Hang Tong Teo, Thomas Merlet, Philippe Pernod

Phase Change Materials (pcm) have been widely used for thermal energy storage due to their high latent heat of fusion. However, PCMs suffer from their very low thermal conductivity which limits heat spreading around the heat source. Without proper thermal conductivity enhancement, melting would...

Magnetically driven superhydrophobic/superoleophilic graphene-based polyurethane sponge for highly efficient oil/water separation and demulsification

A. Jamsaz, E.K. Goharshadi, Alexandre Barras, M. Ifires, Sabine Szunerits, Rabah Boukherroub

Cost-effective and efficient sorbents with emulsion-breaking capability, especially surfactant-stabilized emulsions, are required to remediate oil spills from water. Herein, in situ growth of magnetic Mn0.01Co0.90Fe3O4 (MCFO) nanoparticles (NPs) on reduced graphene oxide (RGO) was performed to...

First-principles thermal transport in amorphous Ge 2 Sb 2 Te 5 at the nanoscale

Thuy-Quynh Duong, Assil Bouzid, Carlo Massobrio, Guido Ori, Mauro Boero, Évelyne Martin

Achieving a precise understanding of nanoscale thermal transport in phase change materials (PCMs), such as Ge 2 Sb 2 Te 5 (GST), is the key of thermal management in nanoelectronics, photonic and neuromorphic applications using non-volatile memories. By resorting to a first-principles approach to...

17 - Interface Response Function in Layered Photonic Materials

Abdellatif Akjouj, L. Dobrzynski, Gaëtan Lévêque, El Houssaine El Boudouti

The interface response theory was presented for any composite material in discrete, continuous, and mixed (partly discrete \textendash partly continuous) spaces (see Chapter 1 of Phononics in Interface Transmission Tutorial Book Series). The aim of this chapter is to show how this theory can be...

An optimal dimensioning method of a green wall structure for noise pollution reduction

Emmanuel Attal, Bertrand Dubus, Thérèse Leblois, Bernard Cretin

This paper concern the optimization of a multilayered green wall structure including substrate and foliage in order to reduce as much as possible backward noise reflection and forward transmission from the wall. Each component involved in the wall structure is fully characterized experimentally to...

14 - One-Dimensional Photonic Waveguide for Filtering and Demultiplexing

Yan Pennec, Bahram Djafari-Rouhani, Abdellatif Akjouj, El Houssaine El Boudouti, Gaëtan Lévêque, L. Dobrzynski

In this chapter, we review numerical simulations of light propagation in one-dimensional photonic semiconductor optical waveguides coupled to one or several lateral stubs. In the presence of one stub, we show that the transmission spectrum contains several narrow dips, provided that the boundaries...
