Effects of Na2SO4 on the optical and structural properties of Cu2ZnSnS4 thin films synthesized using co-electrodeposition technique

Hassan Kirou, Lahoucine Atourki, Khadija Abouabassi, Ali Soltani, Abdelmajid Almaggoussi, Abdeslam Elfanaoui, Khalid Bouabid, M'Barek Nya, Ahmed Ihlal

Abstract In this paper, kesterite films have been prepared by sulfurization of co-electrodeposited Cu–Zn–Sn (CZT) precursor using Na2SO4 as a complexing agent. The structural, morphological, optical and electrical properties of the films have been investigated in details. Adherent layers and pure…

Mechanical properties of porous silicon and oxidized porous silicon by nanoindentation technique

Souheyla Fakiri, Alex Montagne, Khadidja Rahmoun, Alain Iost, Katir Ziouche

A study of mechanical properties of mesoporous silicon (PS) is presented in this article. PS was prepared by electrochemical etching of a heavily doped P++ silicon wafer in a hydrofluoric acid electrolyte. The mechanical properties of PS and oxidized PS obtained by thermal treatment, were…

Device-free human activity microwave detection

Kamel Haddadi, Christophe Loyez

This work describes a device-free activity detection method using a 2.45 GHz link associated to a short-time Fourier transform algorithm. Detection of human activities are exemplary demonstrated to validate the proposed approach considering several scenarios. The simplicity of hardware/software…

Novel three-dimensional carbon nanotube networks as high performance thermal interface materials

Qinyu Kong, Laurence Bodelot, Bérengère Lebental, Yu Dian Lim, Li Lynn Shiau, Boris Gusarov, Chong Wei Tan, Kun Liang, Congxiang Lu, Chuan Seng Tan, Philippe Coquet, Beng Kang Tay

Vertically aligned carbon nanotube (VACNT) arrays are considered as promising thermal interface materials (TIMs) due to their superior out-of-plane thermal conductivities. However the air gaps between adjacent CNTs within the CNT array hinder the in-plane heat transfer, thus significantly degrading…

Neuromorphic Time-Dependent Pattern Classification with Organic Electrochemical Transistor Arrays

Sébastien Pecqueur, Maurizio Mastropasq Talamo, David Guérin, Philippe Blanchard, Jean Roncali, Dominique Vuillaume, F. Alibart

Based on bottom‐up assembly of highly variable neural cells units, the nervous system can reach unequalled level of performances with respect to standard materials and devices used in microelectronic. Reproducing these basic concepts in hardware could potentially revolutionize materials and device…

Effect of graphene layer on the localized surface plasmon resonance (LSPR) and the sensitivity in periodic nanostructure

Mohamed El Barghouti, Abdellatif Akjouj, Abdellah Mir

We study the interaction of gold nanoparticles with a graphene film. Graphene is used as a spacer, as thin as possible, between the gold nanoparticles and the detection dielectric medium, and one of the advantages of graphene is to protect the structure, which allows to avoid the oxidation of…

A validated simulation of energy harvesting with piezoelectric cantilever beams on a vehicle suspension using Bond Graph approach

Barbara Lafarge, Sébastien Grondel, Christophe Delebarre, Eric Cattan

Nowadays, there is a combine effect of piezoelectric material performances and energy harvesting management strategy increase. As the same time, the energy consumption of electrical components and circuits decrease. Thus, this leads to a growing interest in recovering low energy level with…

Continuous-wave infrared optical gain and amplified spontaneous emission at ultralow threshold by colloidal HgTe quantum dots

Pieter Geiregat, Arjan J Houtepen, Laxmi Kishore Sagar, Ivan Infante, Felipe Zapata, Valeriia Grigel, Guy Allan, Christophe Delerue, Dries van Thourhout, Zeger Hens

Abstract Colloidal quantum dots (QDs) raise more and more interest as solution-processable and tunable optical gain materials. However, especially for infrared active QDs, optical gain remains inefficient. Since stimulated emission involves multifold degenerate band-edge states, population…
