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...

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 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...

Resolving the Controversial Existence of Silicene and Germanene Nanosheets Grown on Graphite

Wenbing Peng, Tao Xu, Pascale Diener, Louis Biadala, Maxime Berthe, Xiaodong Pi, Yves Borensztein, Alberto Curcella, Romain Bernard, Geoffroy Prévot, B. Grandidier

The highly oriented pyrolytic graphite (HOPG) surface, consisting of a dangling bond-free lattice, is regarded as a potential substrate for van der Waals heteroepitaxy of two-dimensional layered materials. In this work, the growth of silicon and germanium on HOPG is investigated with scanning...

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...

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...

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,...
