Electrochemical Lithium Insertion into TiO 2 Anatase ALD Thin Films for Li‐Ion Microbatteries: An Atomic‐Scale Picture Provided by Raman Spectroscopy

Ankush Bhatia, Maxime Hallot, Clément Leviel, Pascal Roussel, Jean Pierre Pereira-Ramos, Christophe Lethien, Rita Baddour-Hadjean

Electrochemical lithium (de)intercalation in an atomic layer deposited (ALD) TiO2 anatase thin film deposited on a planar Si /Al2O3/Pt substrate is investigated by Raman spectroscopy. An initial discharge capacity of 63 µAh cm−2 µm−1 (0.5 Li+ mole−1) is reached at C/10 rate, which increases up to...

Deep Reinforcement Learning to Improve Vehicle-to-Vulnerable Road User Communications in C-V2X

Andy Triwinarko, Zoubeir Mlika, Soumaya Cherkaoui, Iyad Dayoub

In this paper, we study the problem of optimizing the performance of vehicle-to-everything (V2X) using deep reinforcement learning techniques while sharing the spectrum between vehicle-to-infrastructure (V2I) links and vehicle-to-vulnerable road users (V2VRU) links in Cellular V2X (C-V2X). The...

A study of DC and RF transconductance for different technologies of HEMT at low and high temperatures

Mohammad Abdul Alim, Anwar Jarndal, Christophe Gaquière, Giovanni Crupi

AbstractWe report on the measured effects of temperature on the DC and RF transconductance for several important HEMT technologies. Six different HEMT transistors were evaluated. Single- and double-heterojunction HEMTs, GaAs and GaN materials, virgin and multi-layer pHEMTs, and matched and...

High-Q Resonant Modes in Periodic Stubbed Structure

Yamina Rezzouk, Mohamed El Ghafiani, Soufyane Khattou, Madiha Amrani, El Houssaine El Boudouti, Abdelkrim Talbi, Bahram Djafari-Rouhani

Bound states in the continuum (BICs) have unique properties and significant applications in photonics. In this paper, we show analytically and experimentally the existence of (N−1) BICs (multi-BICs) in the flat band of a periodic photonic comb made of N stubs of length d2 separated by segments of...

Zak Phase and Topological Tamm States Between Two Photonic Comb Structures

Soufyane Khattou, Yamina Rezzouk, Madiha Amrani, Mohamed El Ghafiani, El Houssaine El Boudouti, Bahram Djafari-Rouhani

We investigate the existence of Tamm states at the interface between two one-dimensional (1D) photonic crystals (PCs) through an analysis of local density of states (LDOS) using the Green’s function method. The PCs are made of a comb-like structure consisting of stubs grafted periodically along a...

Improvement of Silicon Nanowire-Based Photovoltaic Solar Cell with the Integration of CIGS Quantum Wells

Meriem Safi, Abdelkader Aissat, Houcine Guesmi, Jean-Pierre Vilcot

The present work focuses on the modeling and simulation of a new photovoltaic solar cell based on a CIGS/Si nanowire. The study of the effect of inserting quantum wells in a nanowire structure for different characteristic parameters has been done to evaluate the potential of the confinement...
