New barrier layer design for the fabrication of gallium nitride-metal-insulator-semiconductor-high electron mobility transistor normally-off transistor

Flavien Cozette, Bilal Hassan, Christophe Rodriguez, Eric Frayssinet, Rémi Comyn, François Lecourt, Nicolas Defrance, Nathalie Labat, François Boone, Ali Soltani, Abdelatif Jaouad, Yvon Cordier, Hassan Maher

This paper reports on the fabrication of an enhancement-mode AlGaN/GaN metal-insulator-semiconductor-high electron mobility transistor with a new barrier epi-layer design based on double Al 0.2 Ga 0.8 N barrier layers separated by a thin GaN layer. Normally-off transistors are achieved with good…

Elastic Metasurfaces for Deep and Robust Subwavelength Focusing and Imaging

Yabin Jin, Wan Wang, Abdelkrim Khelif, Bahram Djafari-Rouhani

Metasurfaces are planar metamaterials with a flat surface and a subwavelength thickness that are able to shape arbitrary wave fronts such as focusing or imaging. There is a broad interest in the literature about subwavelength focusing and imaging based on bulk metamaterials while the utilization of…

Surface modes in plasmonic stubbed structures

Y. Rezzouk, M. Amrani, S. Khattou, E.H. El Boudouti, Bahram Djafari-Rouhani

We present an analytical and numerical study about the existence of surface localized modes, known as Tamm states, in a one-dimensional (1D) comb-like plasmonic band gap structure. Surface plasmon polaritons (SPPs) waveguides with coupled resonators have been widely studied in recent years, because…

Plasmonic demultiplexer based on induced transparency resonances: Analytical and numerical study

E.H. El Boudouti, Bahram Djafari-Rouhani, M. Amrani, S. Khattou, A. Noual

We study both analytically and numerically the possibility to realize a simple plasmonic Y-shaped demultiplexer made of an input line and two output lines. Each line consisting of a metal-insulator-metal (MIM) waveguide contains a specific resonator made of two stubs grafted at a given position…

Induced transparency based subwavelength acoustic demultiplexers

T. Gu, Y. Cheng, Z. Wen, E.I.H. Ei Boudouti, Y. Jin, Y. Li, Bahram Djafari-Rouhani

Wave demultiplexers transporting desired wavelengths towards proper directions or ports are attracting numerous interests and applications in both physical and engineering areas. In acoustics, there is still a lack of compact and simple designs to achieve demultiplexers in three-port systems. In…

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…

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…
