Epitaxial growth and thermoelectric properties of c-axis oriented Bi 1−x Pb x CuSeO single crystalline thin films

Xiaolin Wu, Jianglong Wang, Hongrui Zhang, Shufang Wang, Shengjun Zhai, Yaguang Li, El Hadj Dogheche, Guangsheng Fu

c-axis oriented Bi1−xPbxCuSeO (0 ≤ x ≤ 0.8) single crystalline thin films have been successfully epitaxially grown on SrTiO3 (001) substrates via the pulsed laser deposition technique. Detailed X-ray diffraction and transmission electron microscopy measurements reveal the excellent c-axis and ab-...

High frequency high breakdown voltage GaN transistors

F Medjdoub, Nicolas Herbecq, Astrid Linge, Malek Zegaoui

In this work, high performance ultrathin barrier GaN devices for high frequency applications are presented. In particular, key features to achieve significant breakdown voltages and high robustness while using sub-10 nm barrier thickness are discussed. It is shown that the thickness of the in-situ...

Développement de capteurs piézoélectriques interdigités flexibles pour la caractérisation ultrasonore des revêtements, Development of flexibles interdigitated piezoelectric sensors for ultrasonic charaterization of coatings

Rafatou Takpara

Ce travail porte sur la réalisation de capteurs interdigités (IDT pour InterDigital Transducer) sur des supports piézoélectriques. L’enjeu est double puisqu’il s’agit premièrement de disposer de capteurs efficaces pour générer des ondes de surface acoustiques (SAW pour Surface Acoustic Wave) afin..., This work deals with the realization of interdigital sensors (IDT for InterDigital Transducer) on piezoelectric substrates. There is a dual challenge since firstly, the aim is to have efficient sensors to generate surface acoustic waves (SAW) in order to characterize the quality of the coatings and...

Controlled mud-crack patterning and self-organized cracking of polydimethylsiloxane elastomer surfaces

Rian Seghir, S. Arscott

Exploiting pattern formation – such as that observed in nature – in the context of micro/nanotechnology could have great benefits if coupled with the traditional top-down lithographic approach. Here, we demonstrate an original and simple method to produce unique, localized and controllable self-...

Ferroelectric Phase Transition, Interfaces Quality, and Stress Evolution of TiO_<i>x</i> /Ba_<i>x</i>Sr_1−<i>x</i>TiO₃ Structures

Areski Ghalem, Freddy Ponchel, Denis Remiens, Tuami Lasri

Ba(Sr,Ti)O3 material presents a remarkable property that lies in the possibility to change the permittivity by applying a dc electric field, i.e., BST is a tunable material. That makes BST a very interesting material for the development of reconfigurable devices in microelectronics. In this study,...

Lipid nanocapsules containing the non-ionic surfactant Solutol HS15 inhibit the transport of calcium through hyperforin-activated channels in neuronal cells

Sylvain Chauvet Chauvet, Alexandre Barras, Rabah Boukherroub, Alexandre Bouron

Hyperforin is described as a natural antidepressant inhibiting the reuptake of neurotransmitters and also activating cation channels. However the blood–brain barrier limits the access to the brain of this biomolecule. To circumvent this problem it was envisaged to encapsulate hyperforin into...

Surveillance passive des milieux réverbérants par corrélation de bruit ambiant : application à la localisation de défauts, Passive defect localization in reverberant plates using correlation of acoustic field

Lynda Chehami

La reconstruction passive des fonctions de Green par corrélation de bruit ambiant suscite aujourd’hui un grand intérêt en contrôle santé intégré (CSI). Dans ce manuscrit, nous proposons une méthode originale reposant sur l’application de cette approche pour détecter et localiser des défauts (..., Green’s functions retrieval from ambient noise correlation has recently drawn a new interest in structural health monitoring. In this manuscript, we propose an original method based on this approach to detect and locate defects (cracks, holes, grooves) in a reverberant thin plate with a limited...
