A focusing technique based on a data spatial diversity at millimetre-wave frequency

Michael Bocquet, Atika Rivenq, Christophe Loyez, Nathalie Rolland

This paper presents a new topology of data coding and data broadcasting exclusively sent to a specific location area. The proposed technique exploits specifically different received signals to focus energy and to rebuild information intelligibly only for a chosen position. By this way, the receiver...

Transport properties of CdSe nanocrystal superlattice

Pierre Capiod, Maxime Berthe, B. Grandidier, Wiel Evers, Daniel Vanmaekelbergh

Two-dimensional materials exhibit exotic electronic properties and high specific surface areas that make them unique to investigate novel physical phenomena. In addition, their two-dimensional geometry is directly compatible with established design and processing approaches from the semiconductor...

Multi-carrier transmission of vectorial modulation schemes using electronic transceivers at 588 GHz

Guillaume Ducournau, P. Szriftgiser, D. Bacquet, Mohammed Zaknoune, Rédha Kassi, Jean-Francois Lampin

A reported is presented on the first communication system using vectorial modulation schemes above 500 GHz. Using Schottky-based electronic technologies at 588 GHz, potentialities of high-level multicarrier modulation schemes for wireless links are analysed. The wireless link is composed of an...

Silicon nanotweezers inside liquid for the real time characterization of DNA degradation under radiotherapy treatment

Grégoire Perret, T. Lacornerie, V. Kumemura, N. Lafitte, H. Guillou, L. Jalabert, E. Lartigau, T. Fujii, Fabrizio Cleri, H. Fujita, Dominique Collard

Tumor cell killing by γ-ray beams in radiotherapy is currently based on a rather empirical understanding of the basic mechanisms and effectiveness of DNA damage by radiation. On the other hand, the mechanical behavior of DNA, e.g., sequence-sensitivity, elastic vs. plastic response, is well...

Threshold voltage study of scaled self-aligned In0.53Ga0.47As metal oxide semiconductor field effect transistor for different source/drain doping concentrations

A. Dehzangi, M.F. Mohd Razip Wee, Nicolas Wichmann, S. Bollaert, M.R. Buyong, B.Y. Majlis

A multi-gate n-type In0.53Ga0.47As metal oxide semiconductor field effect transistor is fabricated using the gate first self-aligned method and air-bridge technology with an 8 nm thick Al2O3 oxide layer. By scaling the gate length down to 200 nm, the effect of two different source/drain doping...

Micro-nanostructured silicon based superomniphobic surfaces

Thi Phuong Nhung Nguyen, Rabah Boukherroub, V. Thomy, Yannick Coffinier

We report on the fabrication of silicon nanostructured superhydrophobic and superoleophobic surfaces also called "superomniphobic" surfaces. For this purpose, silicon interfaces with different surface morphologies, single or double scale structuration, were investigated. These structured...

Silicon-microtube scaffold decorated with anatase TiO2 as a negative electrode for a 3D litium-ion microbattery

Etienne Eustache, Pascal Tilmant, Laurence Morgenroth, Pascal Roussel, Gilles Patriarche, David Troadec, Nathalie Rolland, Thierry Brousse, Christophe Lethien

An optimized scaffold based on silicon microtubes is designed to increase the surface capacity of 3D lithium-ion microbatteries. High-depth, mechanically robust microstructures are fabricated using microelectronic facilities. Conformal deposition of anatase TiO2 is achieved using atomic layer...

Interferometer-based microwave microscopy operating in transmission mode

Kamel Haddadi, Tuami Lasri

A microwave near-field sensing technique with sub-wavelength resolution is proposed for nondestructive local characterization of materials. The method is based on the measurement of a transmission coefficient by means of an association of a vector network analyzer, a hybrid coupler, an evanescent...

2D Maxwell/transport time domain modeling of THz GaN distributed transferred electron device

Christophe Dalle, François Dessenne, Jean-Luc Thobel

In order to investigate the distributed semiconductor device high frequency operation, we are developing a 2D/3D time-domain electromagnetic physical simulator. It is based on a self-consistent solution of both the Maxwell equations and the free carrier macroscopic conservation equation sets issued...
