Capillary-driven horseshoe vortex forming around a micro-pillar

K. Ozawa, H. Nakamura, K. Shimamura, G.F. Dietze, H.N. Yoshikawa, Farzam Zoueshtiagh, K. Kurose, L. Mu, I. Ueno

Hypothesis: Horseshoe vortices are known to emerge around large-scale obstacles, such as bridge pillars, due to an inertia-driven adverse pressure gradient forming on the upstream-side of the obstacle. We contend that a similar flow structure can arise in thin-film Stokes flow around micro-…

Positional and Rotational Molecular Degrees of Freedom at a Roughened Metal–Organic Interface: The Copper–Fullerene System and Its Multiple Structural Phases

María Alfonso Moro, Y. J. Dappe, Sylvie Godey, Thierry Melin, César González, Valérie Guisset, Philippe David, Benjamin Canals, N. Rougemaille, Johann Coraux

The hybrid metal−organic interaction that molecular monolayers experience when deposited on metallic substrates can compete with intermolecular interactions and produce a variety of on-surface orders. The variety is already important when the molecule/substrate interface remains atomically flat.…

Efficient Co/Pt THz spintronic emitter with tunable polarization

A. Buryakov, A. Gorbatova, P. Avdeev, E. Lebedeva, K. Brekhov, A. Ovchinnikov, N. Gusev, E. Karashtin, M. Sapozhnikov, E. Mishina, N. Tiercelin, V.L. Preobrazhensky

We report on the design of a spintronic emitter based on the Pt(3 nm)/Co(3 nm) structure, which enables the control over terahertz radiation polarization. Utilizing the field-induced magnetization rotation that takes place at low magnetic fields of up to 250 Oe at room temperature, we have achieved…

Functionalization of Carbon Surfaces Using the Copper-Catalyzed Diels–Alder Reaction

Denis Ari, Jean-Francois Bergamini, Teresa Rodrigues, Wolfgang Knoll, Charles Cougnon, Essraa Ahmed, Paulius Pobedinskas, Ken Haenen, Nicolas Nuns, Rabah Boukherroub, Sabine Szunerits, Yann R. Leroux

We propose here a new method to functionalize carbon materials via a catalyzed Diels–Alder reaction. In a Diels–Alder reaction, carbon materials can be used as a diene or a dienophile. Here, carbon materials are used as dienes and alkyne-terminated derivatives as dienophiles. Different carbon…

Enhanced Near-Infrared Photoresponse for Efficient Organic Solar Cells Using Hybrid Plasmonic Nanostructures

Yanglin Zhao, Yiran Luo, Shiwei Wu, Chi Wang, Najat Ahmidayi, Gaëtan Lévêque, Xavier Portier, Tao Xu

Nonfullerene organic solar cells (OSCs) have recently made remarkable progress as one of the most promising next-generation photovoltaic technologies. Still, it is highly desirable to enhance the light harvesting for the sake of photoactive layer with a limited thickness. In this work, we developed…

Computational model for predicting structural stability and stress transfer of a new SiGe stressor technique for NMOS devices

Thomas Bordignon, Blandine Duriez, Nicolas Guitard, Romain Duru, Clément Pribat, Jérôme Richy, Shay Reboh, Siddhartha Dhar, Frédéric Monsieur, Thibaud Fache, Zdenek Chalupa, Jean-Michel Hartmann, Pascal Chevalier, Yannick Roelens, Francois Danneville, Sébastien Crémer

A new method to induce tensile stress in a PDSOI NMOS device for RF applications is proposed, which is based on relaxing a SiGe layer built underneath silicon. By means of TCAD simulations, we demonstrate that stress transfer from SiGe to Si occurs by means of at least two different mechanisms:…

Récepteur Wake-up radio basé sur des réseaux de neurones à impulsions pour la détection de séquence

Guillaume Marthe, Claire Goursaud, Laurent Clavier

La consommation énergétique est un point critique dans le domaine de l'Internet des Objets. La Wake-Up Radio permet de laisser le plus possible les noeuds en mode veille et de les réveiller seulement si besoin. Malheureusement, les wakeup radios actuels utilisent des microcontroleurs toujours…

Microwave Optomechanically Induced Transparency and Absorption Between 250 and 450 mK

Sumit Kumar, Dylan Cattiaux, Eddy Collin, Andrew Fefferman, Xin Zhou

High-quality microwave amplifiers and notch-filters can be made from microwave optomechanical systems in which a mechanical resonator is coupled to a microwave cavity by radiation pressure. These amplifiers and filters rely on optomechanically induced transparency (OMIT) and absorption (OMIA),…
