Insertion of an Ultra‐thin Interfacial Aluminium Layer for the Realisation of a Hf0.5Zr0.5O2 Ferroelectric Tunnel Junction.

Benoît Manchon, Greta Segantini, Nicolas Baboux, Pedro Rojo Romeo, Rabei Barhoumi, Dominique Drouin, Infante Ingrid C., F. Alibart, Bertrand Vilquin, Damien Deleruyelle

Herein, the effect of a 2 nm thin aluminum layer inserted between the ferroelectric layer and the top electrode in a TiN/Hf0.5Zr0.5O2/TiN stack deposited by reactive magnetron sputtering is investigated. The oxidation of the interfacial layer during annealing due to scavenging of the Hf0.5Zr0.5O2...

Single Beam Acoustical Tweezers Based on Focused Beams: A Numerical Analysis of Two-Dimensional and Three-Dimensional Trapping Capabilities

Zhixiong Gong, Michael Baudoin

Selective single beam tweezers open tremendous perspectives in microfluidics and microbiology for the micromanipulation, assembly, and mechanical properties testing of microparticles, cells, and microorganisms. In optics, single beam optical tweezers rely on tightly focused laser beams, generating...

USRP RIO-based Testbed for Real-time Blind Digital Modulation Recognition in MIMO Systems

Hayfa Ben Thameur, Iyad Dayoub, Walaa Hamouda

Modulation recognition is one of the key elements in the cognitive radio (CR) technology. Chiefly, automatic modulation recognition (AMR) is a challenging task in such systems. It refers to blindly identifying the modulation type by a CR receiver which is highly recommended for military as well as...

Design of orthogonal filter banks using a multi-objective genetic algorithm for a speech coding scheme

Abdelkader Boukhobza, Nasreddine Taleb, Abdelmalik Taleb-Ahmed, Abdennacer Bounoua

In this work, we propose an optimization scheme based on a multi-objective Genetic Algorithm (GA) for the design of orthogonal filter banks for speech compression. A parameterization is adopted to assure that the resulting filter banks satisfy perfect reconstruction and have at least two vanishing...

Development of the multi-quantum wells structures based on InxGa1-x As1-yNy/GaAs for solar cells applications

Abdelkader Aissat, Rachid Bestam, Manel Boubakeur, Jean-Pierre Vilcot

In order to improve the solar cell efficiency, quantum multi-wells have been implanted into the intrinsic region of the structure. We can absorb the photons that have a lower energy than the bandgap energy. In this work, physical and optical phenomena that influence the efficiency of the solar cell...

Broadband 3-D Shared Aperture High Isolation Nine-Element Antenna Array for On-Demand Millimeter-Wave 5G Applications

Mohammad Alibakhshikenari, Bal Virdee, Valeria Vadalà, Mariana Dalarsson, María Elena de Cos Gómez, Abdullah Alharbi, Shah Nawaz Burokur, Sonia Aïssa, Iyad Dayoub, Francisco Falcone, Ernesto Limiti

The paper presents the results of a novel 3-D shared aperture 3×3 matrix antenna-array for 26 GHz band 5 G wireless networks. Radiation elements constituting the array are hexagonal-shaped patches that are elevated above the common dielectric substrate by 3.35 mm and excited through a metallic rod...

CNTFET‐based ternary address decoder design

Rawan Mohammed, Mohammed Fouda, Ihsen Alouani, Lobna Said, Ahmed Radwan

With the end of Moore's law, new paradigms are investigated for more scalable computing systems. One of the promising directions is to examine the data representation toward higher data density per hardware element. Multiple valued logic (MVL) emerged as a promising system due to its...

Dispersion of surface acoustic waves in thin films at extreme wavelength-to-thickness ratios

Marc Duquennoy, Tahar Kadi, Mohammadi Ouaftouh, Nikolay Smagin, Frédéric Jenot

Surface acoustic waves (SAWs) are sensitive to the presence of a layer on the surface of a material, even if this layer is extremely thin compared to their wavelengths. Given the very slow propagation velocities of SAWs compared to electromagnetic waves, their wavelengths are on the order of 40 μm...

Metasurface-based Filters for High Data Rate THz Wireless Communications: Experimental Validation of a 14 Gbps OOK and 104 Gbps QAM-16 Wireless Link in the 300 GHz band

D. Pirrone, A. Ferraro, D. Zografopoulos, W. Fuscaldo, P. Szriftgiser, Guillaume Ducournau, R. Beccherelli

We demonstrate the effectiveness of frequency selective surface filters in wireless communications at low terahertz (THz) frequencies. Full-wave simulations of pass-band filters designed at 270 GHz and 330 GHz are compared with measurements over 220–360 GHz, showing remarkable agreement. The filter...
