Transport Properties of Methyl-Terminated Germanane Microcrystallites

Davide Sciacca, Maxime Berthe, Bradley Ryan, Nemanja Peric, D. Deresmes, Louis Biadala, Christophe Boyaval, Ahmed Addad, Ophélie Lancry, Raghda Makarem, Sébastien Legendre, Didier Hocrelle, Matthew Panthani, Geoffroy Prévot, Emmanuel Lhuillier, Pascale Diener, B. Grandidier

Germanane is a two-dimensional material consisting of stacks of atomically thin germanium sheets. It’s easy and low-cost synthesis holds promise for the development of atomic-scale devices. However, to become an electronic-grade material, high-quality layered crystals with good chemical purity and...

Plasmonic Tamm states in periodic stubbed MIM waveguides: analytical and numerical study

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

We investigate both analytically and numerically the existence of localized surface modes, the so-called plasmonic Tamm states (PTSs), in a new and versatile platform based on a periodic array of metal-insulator-metal (MIM) stubs grafted along a MIM waveguide. By considering a semi-infinite...

Electrochemical H2 Production using Polypyrazole based Zinc(II) Complex in Alkaline Medium

Mohamed Ibrahim, Gaber A.M. Mersal, Ahmed Fallatah, Rabah Boukherroub, Safaa Abdou, Mohammed Amin

A zinc(II) complex of polypyazole containing ligand namely, [Tp*ZnCl] (Zn1) {Tp* = tris(3,5-dimethylpyrazolyl)borate}, along with its zinc(II) bound hydroxo complex [Tp*Zn–OH] (Zn2) were synthesized and characterized by FT-IR, Raman, 1H NMR techniques and elemental analysis. In alkaline solution (0...

Redox-controlled conductance of polyoxometalate molecular junctions

Cécile Huez, David Guérin, Stéphane Lenfant, Florence Volatron, Michel Calame, Mickael Perrin, Anna Proust, Dominique Vuillaume

We demonstrate the reversible in situ photoreduction of molecular junctions of phosphomolybdate [PMo12O40]3- monolayer self-assembled on flat gold electrodes, connected by the tip of a conductive atomic force microscope. The conductance of the one electron reduced [PMo12O40]4- molecular junction is...

De la théorie à la pratique dans l’enseignement du traitement du signal : initiation à la recherche

Lynda Chehami, Nikolay Smagin, Jamal Assaad, Pierre Campistron, Frédéric Jenot, Emmanuel Moulin

Le débat entre la théorie et la pratique dans l'enseignement sur l'importance de chacun comme base de la formation en Master existe depuis plusieurs années. Ce lien est souvent sous-évaluée et on a tendance à oublier que de la théorie naît la pratique et que la pratique est basée sur la...

Unidirectional Coherent Phonon Emission in an Optomechanic Nanobeam Containing Coupled Cavities

Alexander Korovin, Yan Pennec, Bahram Djafari-Rouhani

Nonreciprocal phonon emission is predicted theoretically from the coherent excitation of two coupled optomechanical cavities arranged along a phoxonic crystal nanobeam. The latter consists of a periodic array of holes and stubs and exhibits simultaneous photonic and phononic bandgaps. It is shown...

Optimized ohmic contacts for InAlGaN/GaN HEMTs

Pierre Ruterana, Marie Pierre Chauvat, Magali Morales, Farid Medjdoub, Piero Gamarra, Christian Dua, Sylvain Delage

In this work, we have carried out a detailed transmission electron microscopy investigation on ohmic contacts in InAl GaN/GaN high electron mobility transistors consisting of Ti/Al/Ni/Au deposited by evaporation electron beam followed by a rapid thermal annealing at 875°C for 30s under N2...

Pairing cells of different sizes in a microfluidic device for immunological synapse monitoring

Faruk Azam Shaik, Clara Lewuillon, Aurélie Guillemette, Bahram Ahmadian, Carine Brinster, Bruno Quesnel, Dominique Collard, Yasmine Touil, Loïc Lemonnier, Mehmet Tarhan

Analyzing cell–cell interaction is essential to investigate how immune cells function. Elegant designs have been demonstrated to study lymphocytes and their interaction partners. However, these devices have been targeting cells of similar dimensions. T lymphocytes are smaller, more deformable, and...

10. Incremental learning of convolutional neural networks in bioinformatics

Wafa Mousser, Salima Ouadfel, Abdelmalik Taleb-Ahmed

In recent years, convolutional neural networks (CNNs) have been widely used in various computer visual recognition tasks and then extensively applied for medical images, particularly for computer-aided diagnosis. Despite this success, CNNs suffer from a catastrophic forgetting issue, making it...
