Analysis of trap states in AlGaN/GaN self-switching diodes via impedance measurements

E. Perez-Martin, D. Vaquero, H. Sanchez-Martin, Christophe Gaquière, V. J. Raposo, T. Gonzalez, J. Mateos, I. Iniguez-De-La-Torre

The presence of trap states in self-switching diodes (SSD) based on an AlGaN/GaN heterojunction has been identified by means of their AC characterization between 75 kHz to 30 MHz in a wide temperature range, from 80 K to 300 K. Measurements allow us to determine two different characteristic…

Design of silver nanoparticles with graphene coatings layers used for LSPR biosensor applications

Mohamed El Barghouti, Abdellatif Akjouj, Abdellah Mir

A new hybrid graphene nanoplasmonic structure, using silver nanoparticles (AgNPs) coated with a graphene film and deposited on a substrate is proposed in this paper. The aim is to obtain a plasmonic response with high sensitivity for plasmonic biosensors. We show, through the calculation of…

Feature fusion via deep random forest for facial age estimation

Oussama Guehairia, A. Ouamane, F. Dornaika, Abdelmalik Taleb-Ahmed

In the last few years, human age estimation from face images attracted the attention of many researchers in computer vision and machine learning fields. This is due to its numerous applications. In this paper, we propose a new architecture for age estimation based on facial images. It is mainly…

Copper‐based metal–organic framework decorated by CuO hair‐like nanostructures: Electrocatalyst for oxygen evolution reaction

Mandana Amiri, Zahra Tofighi, Ali Khodayari, Abolfazl Bezaatpour, Shabnam Sohrabnezhad, Vladyslav Mishyn, Rabah Boukherroub, Sabine Szunerits

We report a Cu-based metal–organic framework (MOF) decorated by CuO nanostructures as an efficient catalyst for the oxygen evolution reaction (OER). MIL-53(Cu) was synthesized by a hydrothermal approach using 1,4-bezenedicarboxylic acid as organic precursor and further annealed at 300°C to form CuO…

Comparison of density of states and scattering parameters in coaxial photonic crystals: theory and experiment

Soufyane Khattou, Madiha Amrani, Abdelkader Mouadili, El Houssaine El Boudouti, Abdelkrim Talbi, Abdellatif Akjouj, Bahram Djafari-Rouhani

We present an analytical and experimental study of the scattering parameters in a one dimensional (1D) symmetric photonic crystal and their relation to the density of states (DOS). The 1D photonic crystal is constituted by N alternating wires and loops that are either inserted horizontally or…

MoS₂-graphene hybrid nanostructures enhanced localized surface plasmon resonance biosensors

Mohamed El Barghouti, Abdellatif Akjouj, Abdellah Mir

We propose a new configuration of a localized surface plasmon resonance (LSPR) biosensor that is based on MoS₂-graphene hybrid structures for ultrasensitive detection of molecules. The performance parameters of the proposed biosensor are defined in terms of absorption and…

Dimensional and mechanical characterization of metallic thin films based on the measurement of surface acoustic waves dispersion with Slant Stack transform

Tahar Kadi, Marc Duquennoy, Dame Fall, Nikolay Smagin, Bogdan Piwakowski, Mohammadi Ouaftouh, Frédéric Jenot

In this study, an ultrasonic method for characterizing thin films based on the dispersion of the first Rayleigh mode is presented. The principle of surface acoustic waves (SAW) generation using a broadband transducer and their detection is detailed. It is shown that over a frequency range between…

[Invited] Three-dimensional trapping and assembly with synchronized spherical acoustical vortices

Zhixiong Gong, Michael Baudoin

Micro-objects and micro-organisms trapping and assembly with acoustical tweezers would open new horizons in microrobotics and microbiology, e.g., selective cells fusion and aggregation. Our previous work [Gong and Baudoin, Phys. Rev. Appl. 12, 024045 (2019)] demonstrates theoretically in two…

[Invited] Equivalence of three-dimensional acoustic radiation force and torque formulas based on angular spectrum and multipole expansion methods

Zhixiong Gong, Michael Baudoin

Acoustic radiation force (ARF) or torque (ART) can be derived by integrating the time-averaged linear and angular radiation stress tensor (the flux of momentum tensor) over a far-field standard spherical surface including an arbitrarily shaped target. Following this idea, there are three sets of…

Heartbeat-based synchronization scheme for the human intranet: modeling and analysis

Robin Benarrouch, Ali Moin, Flavien Solt, Antoine Frappé, Andreia Cathelin, Andreas Kaiser, Jan Rabaey

Sharing a common clock signal among the nodes is crucial for communication in synchronized networks. This work presents a heartbeat-based synchronization scheme for body-worn nodes. The principles of this coordination technique combined with a puncture-based communication method are introduced.…
