Scattering-matrix approach for a quantitative evaluation of the topological protection in valley photonic crystals

Gaëtan Lévêque, Yan Pennec, Pascal Szriftgiser, Alberto Amo, Alejandro Martínez

The realization of photonic crystal waveguides with high topological protection enables robust light propagation against defect-induced scattering. It should allow the design of very compact devices by exploiting guiding through sharp bends with low losses and backreflection. In this work we use...

Higher-order mode filtering by a resistive layer

Svetlana Kuznetsova, Yves Aurégan, Vincent Pagneux

A method for filtering higher-order acoustic modes using a resistive layer is proposed and applied to a two-dimensional rectangular waveguide with a quiescent fluid. An analogue of Cremer's criterion is discussed and used to obtain the optimal modal attenuation of the non-planar waves while...

Design and fabrication of nanometer measurement platform for better understanding of silicon mechanical properties

Maciej Haras, Jean-François Robillard, Thomas Skotnicki, Emmanuel Dubois

Semiconductor industry is experiencing unprecedented growth, still driven by Moore's law, which is continually delivering devices with improved performance at lower costs. The continuation of this development places the industry in a divergent trade-off between economic attractiveness,...

The Effect of C60 and Pentacene Adsorbates on the Electrical Properties of CVD Graphene on SiO2

Jacopo Oswald, Davide Beretta, Michael Stiefel, Roman Furrer, Dominique Vuillaume, Michel Calame

Graphene is an excellent 2D material for vertical organic transistors electrodes due to its weak electrostatic screening and field-tunable work function, in addition to its high conductivity, flexibility and optical transparency. Nevertheless, the interaction between graphene and other carbon-based...

Steady vs. Dynamic Contributions of Different Doped Conducting Polymers in the Principal Components of an Electronic Nose’s Response

Wiem Haj Ammar, Aicha Boujnah, Aimen Boubaker, Adel Kalboussi, Kamal Lmimouni, Sébastien Pecqueur

Multivariate data analysis and machine-learning classification become popular tools to extract features without physical models for complex environments recognition. For electronic noses, time sampling over multiple sensing elements must be a fair compromise between a period sufficiently long to...

High-field 1/f noise in hBN-encapsulated graphene transistors

A. Schmitt, D. Mele, Michael Rosticher, T. Taniguchi, K. Watanabe, C. Maestre, C. Journet, V. Garnier, Gwendal Fève, J. Berroir, Christophe Voisin, B. Plaçais, Emmanuel Baudin

Low-frequency 1/f noise in electronics is a conductance fluctuation, that has been expressed in terms of a mobility ”α-noise” by Hooge and Kleinpenning. Understanding this noise in graphene is a key towards high-performance electronics. Early investigations in diffusive graphene have pointed out a...

0D/2D Co3O4/Ti3C2 MXene Composite: A Dual-Functional Electrocatalyst for Energy-Saving Hydrogen Production and Urea Oxidation

Yi Zhang, Zhaohui Zhang, Ahmed Addad, Qi Wang, Pascal Roussel, Mohammed Amin, Sabine Szunerits, Rabah Boukherroub

Electrocatalytic water splitting to produce hydrogen (H2) is a sustainable way of meeting energy demands at no environmental cost. However, the sluggish anodic reaction imposes a considerable overpotential requirement. By contrast, the electrocatalytic urea oxidation reaction offers the prospect of...

Preparation of Flower-Shaped Co-Fe Layer Double Hydroxide Nanosheets Loaded with Pt Nanoparticles by Corrosion Engineering for Efficient Electrocatalytic Water Splitting

Zhao-Hui Zhang, Yi Zhang, Alexandre Barras, Ahmed Addad, Pascal Roussel, Long-Cheng Tang, Mohammed Amin, Sabine Szunerits, Rabah Boukherroub

The development of high-performance and cost-effective hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) electrocatalysts is highly required for electrochemical water splitting. The sluggish reaction kinetics, poor stability, and complicated processing restrict the practical...
