Graphene-based one-dimensional terahertz phononic crystal: band structures and surface modes

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

In this paper, we provide a theoretical and numerical study of the acoustic properties of infinite and semi-infinite superlattices made out of graphene-semiconductor bilayers. In addition to the band structure, we emphasize the existence and behavior of localized and resonant acoustic modes…

A computationally efficient nonlinear dynamic model for cMUT based on COMSOL and MATLAB/Simulink

Yan Wang, Le-Ming He, Ziwei Li, Wei-Jiang Xu, Junyan Ren

Using the plate capacitance model, capacitive micromachined ultrasound transducers (cMUT) cells can be simulated. We present a hybrid model that predicts the dynamic behavior of a cMUT cell with uneven membrane and partial coverage electrode. COMSOL Multiphysics was used to calculate the stationary…

Rapid and sensitive identification of uropathogenic Escherichia coli using a surface-enhanced-Raman-scattering-based biochip

Cristina-Cassiana Andrei, Anne Moraillon, Stephanie Lau, Nordin Félidj, Nao Yamakawa, Julie Bouckaert, Eric Larquet, Rabah Boukherroub, Francois Ozanam, Sabine Szunerits, Anne Chantal Gouget-Laemmel

Rapid, selective and sensitive sensing of bacteria remains challenging. We report on a highly sensitive and reproducible surface-enhanced Raman spectroscopy (SERS)-based sensing approach for the detection of ur-opathogenic Escherichia coli (E. coli) bacteria in urine. The assay is based on the…

Excitation Intensity and Temperature-Dependent Performance of InGaN/GaN Multiple Quantum Wells Photodetectors

Alessandro Caria, Carlo de Santi, Ezgi Dogmus, F Medjdoub, Enrico Zanoni, Gaudenzio Meneghesso, Matteo Meneghini

In this article, we investigate the behavior of InGaN-GaN Multiple Quantum Well (MQW) photodetectors under different excitation density (616 µW/cm 2 to 7.02 W/cm 2) and temperature conditions (from 25 • C to 65 • C), relating the experimental results to carrier recombination/escape dynamics. We…

High performance flexible hybrid supercapacitors based on nickel hydroxide deposited on copper oxide supported by copper foam for a sunlight-powered rechargeable energy storage system

Min Li, Ahmed Addad, Pascal Roussel, Sabine Szunerits, Rabah Boukherroub

Herein, an integrated system combining solar cells with a hybrid supercapacitor for operating a homemade windmill device was assembled, achieving energy conversion, storage and utilization. As a candidate for positive electrode of hybrid supercapacitor devices, battery-like Ni(OH)2@CuO@Cu binder-…

Experimental study on the impact of antenna characteristics on non-stationary V2I channel parameters in tunnels

Marwan Yusuf, Emmeric Tanghe, Pierre Laly, Frederic Challita, Bart Lannoo, Rreze Halili, Rafael Berkvens, Maarten Weyn, Luc Martens, Davy Gaillot, M. Lienard, Wout Joseph

This paper analyses the experimentally-assessed dual-polarized (DP) mobile channel in a tunnel environment at 1.35 GHz under traffic conditions. We investigate the impact of antenna polarization and radiation pattern on the non-stationary vehicle-to-infrastructure (V2I) channel. Basic channel…
