Revisiting Coulomb diamond signatures in quantum Hall interferometers

N. Moreau, S. Faniel, Fabrice Martins, L. Desplanque, X. Wallart, S. Melinte, V. Bayot, B. Hackens

Coulomb diamonds are the archetypal signatures of Coulomb blockade, a well-known charging effect mainly observed in nanometer-sized electronic islands tunnel-coupled with charge reservoirs. Here, we identify apparent Coulomb diamond features in the scanning gate spectroscopy of a quantum point…

Surface-based protein domains retrieval methods from a SHREC2021 challenge

Florent Langenfeld, Tunde Aderinwale, Charles Christoffer, Woong-Hee Shin, Genki Terashi, Xiao Wang, Daisuke Kihara, Halim Benhabiles, Karim Hammoudi, Adnane Cabani, Feryal Windal, Mahmoud Melkemi, Ekpo Otu, Reyer Zwiggelaar, David Hunter, Yonghuai Liu, Léa Sirugue, Huu-Nghia Nguyen, Tuan-Duy Nguyen, Vinh-Thuyen Nguyen-Truong, Danh Le, Hai-Dang Nguyen, M-T Tran, Matthieu Montes

Proteins are essential to nearly all cellular mechanism and the effectors of the cells activities. As such, they often interact through their surface with other proteins or other cellular ligands such as ions or organic molecules. The evolution generates plenty of different proteins, with unique…

A Gradual Resource Allocation Technique for Massive MIMO-NOMA

Eric Pierre Simon, Joumana Farah, Pierre Laly, Gauthier Delbarre

In this paper, a new perspective for channel allocation and user pairing is proposed for a crowded downlink system using massive multiple-input multiple-output (MIMO), non-orthogonal multiple access (NOMA), and Zero-forcing (ZF) beamforming. The proposed user clustering technique allocates users to…

Characterization of IEEE 802.11 communications and detection of low power jamming attacks in noncontrolled environment based on a clustering study

Jonathan Villain, Virginie Deniau, Christophe Gransart, Anthony Fleury, Eric Pierre Simon

Wireless connections are more and more used in different applications and in public areas for services to consumers but also for handling (sometimes) sensitive communications (for instance in railway systems or for remote video monitoring systems). Such systems can have to face different kind of…

Bio‐Inspired Adaptive Sensing through Electropolymerization of Organic Electrochemical Transistors

Mahdi Ghazal, Michel Daher Mansour, Corentin Scholaert, Thomas Dargent, Yannick Coffinier, Sébastien Pecqueur, F. Alibart

Organic electrochemical transistors are considered today as a key technology to interact with a biological medium through their intrinsic ionic-electronic coupling. In this paper, the authors show how this coupling can be finely tuned (in operando) post-microfabrication via the…

The holy grail of pyrene-based surface ligands on the sensitivity of graphene-based field effect transistors

Vladyslav Mishyn, Adrien Hugo, Teresa Rodrigues, Patrik Aspermair, Henri Happy, Leonel Marques, Charlotte Hurot, Riadh Othmen, Vincent Bouchiat, Rabah Boukherroub, Wolfgang Knoll, Sabine Szunerits

Graphene has received intensive research interest due to its remarkable charge mobility, and the efforts in the use of graphene-based field effect transistors (GFETs) for the sensing of biological biomarkers is on the rise. Because of the high non-specific protein adsorption on graphene, well-…

Sensitivity-Bandwidth Optimization of PMUT with Acoustical Matching Using Finite Element Method

Le-Ming He, Wei-Jiang Xu, Yan Wang, Jia Zhou, Jun-Yan Ren

A new model in finite element method to study round-trip performance of piezoelectric micromachined ultrasonic transducers (pMUTs) is established. Most studies on the performance of pMUT are based only on the transmission sensibility, but the reception capacity is as much important as the…

Short bends using curved mirrors in silicon waveguides for terahertz waves

Mattias Verstuyft, Elias Akiki, Mathias Vanwolleghem, Guillaume Ducournau, Jean-Francois Lampin, Benjamin Walter, Fuanki Bavedila, Édouard Lebouvier, Marc Faucher, Bart Kuyken

Dielectric waveguides are capable of confining and guiding terahertz waves along sub-wavelength sized structures. A small feature size allows for a denser integration of different photonic components such as modulators, beam-splitters, wavelength (de)multiplexers and more. The integration of…

Unlocking synchrotron sources for THz spectroscopy at sub-MHz resolution

T. Hearne, Marie-Hélène Mammez, Dominique Mammez, M.-A. Martin-Drumel, P. Roy, O. Pirali, Sophie Eliet, S Barbieri, Francis Hindle, Gaël Mouret, Jean-Francois Lampin

Synchrotron radiation (SR) has proven to be an invaluable contributor to the field of molecular spectroscopy, particularly in the terahertz region (1-10 THz) where its bright and broadband properties are currently unmatched by laboratory sources. However, measurements using SR are currently limited…
