Trap-related frequency dispersion of zero-bias microwave responsivity at low temperature in GaN-based self-switching diodes

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

The zero-bias microwave detection capability of self-switching diodes (SSDs) based on AlGaN/GaN is analyzed in a wide temperature range, from 10 K to 300 K. The measured responsivity shows an anomalous enhancement at low temperature, while the detected voltage exhibits a roll-off in frequency,...

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...

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...

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...

[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....
