Resolving the structure of the striped Ge layer on Ag ( 111 ) : Ag 2 Ge surface alloy with alternate fcc and hcp domains

K. Zhang, D. Sciacca, A. Coati, R. Bernard, Yves Borensztein, Pascale Diener, B. Grandidier, Isabelle Lefebvre, M. Derivaz, C. Pirri, Geoffroy Prévot

Two-dimensional (2D) honeycomb lattices beyond graphene, such as germanene, promise new physical properties such as quantum spin Hall effect. While there have been many claims of growth of germanene, the lack of precise structural characterization of the epitaxial layers synthesized hinders further…

Microwave optomechanical measurement of non-metallized SiN strings at mK temperatures

Sumit Kumar, Yannick Klass, Baptiste Alperin, Srisaran Venkatachalam, Xin Zhou, Eva Weig, Eddy Collin, Andrew Fefferman

The mechanical properties of amorphous materials (glasses) at low temperatures are dominated by effects of low energy excitations that are thought to be atomic-scale tunneling two level systems (TTLS). In nanometer-scale glass samples, the temperature dependence of the sound speed and dissipation…

Les insulinosécrétagogues auront-ils un sexe ?

Amar Abderrahmani, Valérie Plaisance, Valérie Pawlowski, Michele Lodato, Sabine Szunerits, Rabah Boukherroub

Le dimorphisme sexuel dans le contrôle de la glycémie existe bel et bien. Lors d’une épreuve d’hyperglycémie provoquée, la glycémie chez les femmes est plus basse, en raison d’une vidange gastrique plus lente et d’une sensibilité à l’insuline plus élevée que celles des hommes. Outre ce fait, à…

Multi-layer MoS2-Based Plasmonic Gold Nanowires at Near-Perfect Absorption for Energy Harvesting

Zakariae Oumekloul, Shuwen Zeng, Younes Achaoui, Abdellah Mir, Abdellatif Akjouj

One of the biggest challenges in relation to the modernistic vision of smart city technology is to provide confdent autonomous energy, notably in terms of power storage. If you want to change an existing lifestyle, you cannot ignore the basic concepts collected from basic physics. The subject of…

Morphological influence of BiVO4 nanostructures on peroxymonosulfate activation for highly efficient catalytic degradation of rhodamine B

Khawla Missaoui, Rachid Ouertani, Elyes Jbira, Rabah Boukherroub, Brahim Bessaïs

Bismuth vanadate (BiVO4) nanostructured films were prepared and successfully applied for peroxymonosulfate (PMS) activation for the degradation of rhodamine B (RhB) in aqueous solution. The BiVO4 thin films were obtained by thermal reaction between electrodeposited bismuth (Bi) films and vanadium…

Mildly-doped polythiophene with triflates for molecular recognition

Aicha Boujnah, Aimen Boubaker, Adel Kalboussi, Kamal Lmimouni, Sébastien Pecqueur

Organic semiconductors have enough molecular versatility to feature chemo-specific electrical sensitivity to large families of chemical substituents via different intermolecular bonding modes. This study demonstrates that one single conducting polymer can be tuned to either discriminate water-,…

Numerical study of high-efficient and high-speed In0.1Ga0.9 N/GaN multiple quantum well photodiodes

Okba Saidani, Souad Tobbeche, El Hadj Dogheche, Bandar Alshehri

This paper presents a numerical simulation study of p-i-n photodiodes based on In0.1Ga0.9 N/GaN multiple quantum wells (MQWs) of 2.5-nm-thick In0.1Ga0.9 N QWs and 12-nm-thick GaN barriers embedded into the intrinsic regions. The device performance is evaluated by investigating both the spectral and…
