Addressing the exciton fine structure in colloidal nanocrystals: the case of CdSe nanoplatelets

Elena V Shornikova, Louis Biadala, Dmitri R Yakovlev, Victor F Sapega, Yuri G Kusrayev, Anatolie Mitioglu, Mariana V Ballottin, Peter C M Christianen, Vasilii V Belykh, Mikhail V Kochiev, Nikolai N Sibeldin, Aleksandr A Golovatenko, Anna V Rodina, Nikolay A Gippius, Alexis Kuntzmann, Ye Jiang, Michel Nasilowski, Benoit Dubertret, Manfred Bayer

We study the band-edge exciton fine structure and in particular its bright-dark splitting in colloidal semiconductor nanocrystals by four different optical methods based on fluorescence line narrowing and time-resolved measurements at various temperatures down to 2 K. We demonstrate that all these…

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,…

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…

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…

Measurement of the thermal conductivity of flexible biosourced polymers using the 3-omega method

Ghizlane Boussatour, Pierre-Yves Cresson, Benoit Genestie, Nicolas Joly, Jean-François Brun, T. Lasri

The thermal conductivity of flexible biosourced polymers was measured by the 3-omega method. Two biopolymers were investigated: the polylactic acid (PLA), a widely used commercial biodegradable one, and the cellulose palmitate (CP), a hydrophobic biosourced material developed in the laboratory,…

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…

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…

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…
