A bidirectional short range low power and high data rate W-Band transceiver for network on chip

Dipal Ghosh, Antoine Frappé, Christophe Loyez, Andreia Cathelin

A low power wireless transceiver architecture is proposed along with full system integration for network on chip communication, operating in millimeter wave W Band (100 GHz) frequency. The transceiver is designed in 28 inn FDSOI CMOS technology for a data rate of nearly 20 Gbps, with an energy…

Structural determination of bilayer graphene on SiC(0001) using synchrotron radiation photoelectron diffraction

I. Razado-Colambo, J. Avila, D. Vignaud, S. Godey, X. Wallart, D P Woodruff, M.C. Asensio

In recent years there has been growing interest in the electronic properties of ‘few layer’ graphene films. Twisted layers, different stacking and register with the substrate result in remarkable unconventional couplings. These distinctive electronic behaviours have been attributed to structural…

Nano-structured top contact with low optical polarization dependence for THz generation using photodiodes

Sara Bretin, Maximilien Billet, Emilien Peytavit, Francois Vaurette, Christophe Coinon, X. Wallart, Jean-Francois Lampin, Malek Zegaoui, Guillaume Ducournau, Mohammed Zaknoune

Uni-travelling carrier photodiode (UTC-PD) with different top optical and electrical accesses are proposed towards optical polarization sensitivity reduction. With the optimized structure, only 1 percent dependence in optical polarization is obtained while ensuring good RF access. Measurements up…

Effective and rapid technique for temporal response modeling of surface acoustic wave interdigital transducers

Dame Fall, Marc Duquennoy, Mohammadi Ouaftouh, Bogdan Piwakowski, Frédéric Jenot

Surface Acoustic Wave Interdigital Transducers (SAW-IDT) has a considerable application potential for characterization of properties of thin layers, coatings and functional surfaces. For optimization of these SAW-IDTs, it is necessary to study various SAW-IDT configurations by varying the number of…

A time-domain model and experimental validation of the acoustic field radiated by air-coupled transducers

Ji Li, Bogdan Piwakowski

This paper presents a time-domain model for the prediction of an acoustic field in an air-coupled, noncontact, ultrasonic setup, which includes an air-coupled Emitter, the Propagation space and an aircoupled Receiver (EPR). The model takes into account the finite size of the aperture receiver,…

Performance evaluation of an IMDD optical OFDM-CDMA system

Sofien Mhatli, Hichem Mrabet, Elias Giacoumidis, Iyad Dayoub

In this paper, we propose a modulation technique for passive optical networks that harnesses two-dimensional prime hop system optical code division multiplexing access (OCDMA) and optical orthogonal frequency-division multiplexing (OFDM) for intensity modulation with direct-detection (IMDD) to…

Electronic Biosensing with Flexible Organic Transistor Devices

Caroline Kotlowski, Patrik Aspermair, Hadayat Ullah Khan, Ciril Reiner-Rozman, Josef Breu, Sabine Szunerits, Jang-Joo Kim, Zhenan Bao, Christoph Kleber, Paolo Pelosi, Wolfgang Knoll

In this short review, we summarize the design and implementation of organic semiconducting materials-based field-effect transistors (OFETs) and the fabrication and use of reduced graphene-oxide field-effect transistors (rGO–FETs) as flexible transducers for electronic biosensing. We demonstrate…

Efficient functional cyst formation of biliary epithelial cells using microwells for potential bile duct organisation in vitro

Astia Rizki-Safitri, Marie Shinohara, Yasushi Miura, Mathieu Danoy, Minoru Tanaka, Atsushi Miyajima, Yasuyuki Sakai

Establishing a bile duct in vitro is valuable to obtain relevant hepatic tissue culture systems for cellbased assays in chemical and drug metabolism analyses. The cyst constitutes the initial morphogenesis for bile duct formation from biliary epithelial cells (BECs) and serves the main building…

Cation discrimination in organic electrochemical transistors by dual frequency sensing

Sébastien Pecqueur, Dominique Vuillaume, David Guérin, F. Alibart

In this work, we propose a strategy to sense quantitatively and specifically cations, out of a single organic electrochemical transistor (OECT) device exposed to an electrolyte. From the systematic study of six different chloride salts over 12 different concentrations, we demonstrate that the…
