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...

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...

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...

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...

A comparative preprocessing study for softcast video transmission

Anthony Trioux, François-Xavier Coudoux, Patrick Corlay, M Gharbi

An original wireless video transmission scheme called SoftCast has been recently proposed to deal with the issues encountered in conventional wireless video broadcasting systems such as cliff effect. In this paper, we first review the SoftCast scheme. We then analyze and compare two simple...

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,...
