Optimization of a tunable piezoelectric resonator using phononic crystals with periodic electrical boundary conditions

Marie-Fraise Ponge, Bertrand Dubus, Christian Granger, Jerome O. Vasseur, Mai Pham Thi, Anne-Christine Hladky

Piezoelectric phononic crystals with periodic short-circuit conditions exhibit Bragg band gaps. They are used to design a Fabry-Perot cavity. The design of the device enables a modification of cavity length by a spatial shift of electrical boundary conditions. The resonator is thus tunable and a…

Hexamolybdenum Clusters Supported on Graphene Oxide: Visible-Light Induced Photocatalytic Reduction of Carbon Dioxide into Methanol

Pawan Kumar, Harshal P. Mungse, Stéphane Cordier, Rabah Boukherroub, Om P. Khatri, Suman L Jain

Hexamolybdenum (Mo6) cluster-based compounds namely Cs2Mo6Bri8Bra6 and (TBA)2Mo6Bri8Bra6 (TBA = tetrabutylammonium) were immobilized on graphene oxide (GO) nanosheets by taking advantage of the high lability of the apical bromide ions with oxygen-functionalities of GO nanosheets. The loading of Mo6…

Multiport Reflectometer Based on Subtractive Mixing

Abdelhatif El Fellahi, Kamel Haddadi, David Glay, Tuami Lasri

A compact multiport reflectometer using a new subtractive mixing scheme for the determination of reflection coefficients in the frequency range of 1-10 GHz is proposed. Compared with classical multiport reflectometers, the architecture proposed reduces the design complexity. Comparison between…

Measurement Accuracy and Repeatability in Near-Field Scanning Microwave Microscopy

S. Gu, Kamel Haddadi, A. El Fellahi, Gilles Dambrine, T. Lasri

We report on the accuracy and repeatability tests for near-field scanning microwave microscopy applications by associating a network analyzer and an evanescent microwave probe (EMP). A broadband matching network based on an interferometric technique is used to achieve a strong electromagnetic…

A planar micro thermoelectric generator with high thermal resistance

Zheng Yuan, Katir Ziouche, Zahia Bougrioua, Pascale Lejeune, Tuami Lasri, Didier Leclercq

This paper presents the modelling, design, fabrication and characterization of a planar micro thermoelectric generator (μTEG) which is able to convert waste heat into a few microwatts of electrical power. In order to get a better performance under a large variety of heat sources even if their…

Optically-pumped continuous-wave terahertz sources

Philipp Latzel, Fabio Pavanello, Emilien Peytavit, Mohammed Zaknoune, Guillaume Ducournau, X. Wallart, Jean-Francois Lampin

Recently we have improved the efficiency and the output power of our optically pumped continuous-wave THz sources. These sources are based on the beating of two laser lines in a wide bandwidth photodetector. Its intrinsic nonlinear behaviour is used to produce a beatnote at the frequency difference…

On the use of tracking loops for low-complexity multi-path channel estimation in OFDM systems

Huaqiang Shu, Eric Pierre Simon, Laurent Ros

—This paper treats pilot aided multi-path channel estimation with tracking loops for OFDM systems under slow to moderate fading conditions. Recent works have presented theoretical results for the tuning of second-order and third-order tracking loops in the particular context of Jakes's Doppler…

Toward quantitative modeling of silicon phononic thermocrystals

V. Lacatena, M. Haras, J.F. Robillard, S. Monfray, T. Skotnicki, Emmanuel Dubois

The wealth of technological patterning technologies of deca-nanometer resolution brings opportunities to artificially modulate thermal transport properties. A promising example is given by the recent concepts of "thermocrystals" or "nanophononic crystals" that introduce regular…
