Compact localized boundary states in a quasi-1D electronic diamond-necklace chain

S. Kempkes, Pierre Capiod, S. Ismaili, J. Mulkens, L. Eek, I. Swart, C. Morais Smith

Zero-energy modes localized at the ends of one-dimensional (1D) wires hold great potential as qubits for fault-tolerant quantum computing. However, all the candidates known to date exhibit a wave function that decays exponentially into the bulk and hybridizes with other nearby zero-modes, thus...

Explainable root cause and pathway analysis with robust and adaptive statistics

Mohamed Amine Atoui, Vincent Cocquempot

Accurate detection of faults is desired to reduce risks and costs. The identification of the propagation path of faults and the system’s variables responsible of faulty operating conditions is also paramount. This paper presents a new alternative to a well-known Bayesian network-based approach to...

Comparaison de formes d'ondes pour radar MIMO

Hind Ait Taleb, Valentine Wasik, Abigael Taylor, Yassin El Hillali

Le but du radar est de détecter des cibles et de déterminer certaines de leurs caractéristiques (distance, vitesse, angle). Ce papier s'intéresse à la comparaison des signaux élémentaires utilisés avec différentes méthodes de génération de formes d'ondes pour un radar MIMO de détection et...

Wafer-Scale Performance Mapping of Magnetron-Sputtered Ternary Vanadium Tungsten Nitride for Microsupercapacitors

Khac Huy Dinh, Kevin Robert, Joelle Thuriot-Roukos, Marielle Huvé, Pardis Simon, David Troadec, Christophe Lethien, Pascal Roussel

To power Internet of Things applications, new materials are currently being investigated as efficient electrodes for micro-supercapacitor. In the recent years, multicationic materials were demonstrated to be an attractive new class of materials for electrodes. In this study, we deposited vanadium...

A fuzzy/possibility approach for area coverage in wireless sensor networks

Adda Boualem, Cyril de Runz, Marwane Ayaida, Herman Akdag

The literature approaches, devoted to sensor improve network coverage, are deterministic in terms of deployment environment and node configuration parameters. Nevertheless, this type of approaches has not proven to be very successful in uncertain deployment environments. This paper aims to deal...

Fiber-tip spintronic terahertz emitters

Felix Paries, Nicolas Tiercelin, Geoffrey Lezier, Mathias Vanwolleghem, Felix Selz, Maria-Andromachi Syskaki, Fabian Kammerbauer, Gerhard Jakob, Martin Jourdan, Mathias Kläui, Zdenek Kaspar, Tobias Kampfrath, Tom Seifert, Georg von Freymann, Daniel Molter

Spintronic terahertz emitters promise terahertz sources with an unmatched broad frequency bandwidth that are easy to fabricate and operate, and therefore easy to scale at low cost. However, current experiments and proofs of concept rely on free-space ultrafast pump lasers and rather complex...

Ultrafast Modulation of Polarization in Spintronic THz Emitters Enhanced by Field Induced Spin Reorientation Transition

Geoffrey Lezier, Pierre Koleják, Jean-Francois Lampin, Kamil Postava, Mathias Vanwolleghem, Nicolas Tiercelin

We demonstrate an efficient and simple modulation of the polarization in Spin-tronic Terahertz Emitters, by rapid switching of the magnetization using high-frequency magnetic field, enhanced by field induced Spin Reorientation Transition (SRT). The instability of the magnetic layer at the...

High Throughput Characterization Methods at the Wafer Scale for Sputtered Films Used in Micro-Supercapacitors and Li-Ion Micro-Batteries

Pascal Roussel, Aiman Jrondi, Khac Huy Dinh, Bukola Jolayemi, Clément Leviel, Maxime Hallot, Christophe Lethien

The emergence of new miniaturized and autonomous electronic technologies leads to a request of efficient microdevices for energy storage. The development of thin film Li-ion micro-batteries or micro-supercapacitors is an interesting way to power connected sensors, as their manufacturing method is...

In-Depth Investigation of Manganese Dioxide as Pseudocapacitive Electrode in Lithium- and Sodium-Doped Ionic Liquids

Thibaud Guillemin, Camille Douard, Anthony Impellizzeri, Christopher Ewels, Bernard Humbert, Christophe Lethien, Scott Wilfred Donne, Jean Le Bideau, Thierry Brousse

We investigate the contribution of pseudocapacitance to the overall capacitance of MnO2 electrodes in pure and alkaline-doped ionic liquids via two spectroscopic methods: step potential electrochemical spectroscopy (SPECS) and in situ Raman spectroscopy. For both characterization methods, thin-film...
