Unconventional thin-film thermoelectric converters : structure, simulation, and comparative study

Maciej Haras, Valeria Lacatena, Stéphane Monfray, J.F. Robillard, Thomas Skotnicki, Emmanuel Dubois

Bi2Te3 or Sb2Te3 are the materials most widely used in thermoelectric generators (TEG) operating near room temperature. These materials are, however, environmentally harmful, expensive, and incompatible with complementary metal-oxide semiconductor technology, in contrast to silicon (Si), germanium…

Diffusion based kinetic selectivity modulation of enzymatic proteolysis in a microfluidic reactor : experimental analysis and stochastic modeling

Adil Elagli, Simon Laurette, A. Treizebre, Bertrand Bocquet, Renato Froidevaux

Microreactors enable new experimental ways for enzyme engineering. In this context, we show that the liquid-liquid parallel laminar flows in microchannels cause a kinetic selectivity modification of proteolytic enzymatic reaction involving hemoglobin and pepsin, reaction that generates numerous…

Thermoelectric infrared microsensors based on a periodically suspended thermopile integrating nanostructured Ge/SiGe quantum dots superlattice

Katir Ziouche, G. Savelli, Zahia Bougrioua, D. Hauser, P. Lejeune, P.M. Michon, Tuami Lasri, Didier Leclercq

This paper presents an original integration of polycrystalline SiGe-based quantum dots superlattices (QDSL) into Thermoelectric (TE) planar infrared microsensors (μSIR) fabricated using a CMOS technology. The nanostructuration in QDSL results into a considerably reduced thermal conductivity by a…

On the correlation between kink effect and effective mobility in InAlN/GaN HEMTs

Philippe Altuntas, N. Defrance, Marie Lesecq, Alain Agboton, Rezki Ouhachi, Etienne Okada, Christophe Gaquière, Jean-Claude de Jaeger, Éric Frayssinet, Yvon Cordier

This paper reports on the kink effect observed in InAlN/GaN high electron mobility transistors. Electrical characterizations were carried out to point out the influence of this phenomenon on transistor behaviour. It is demonstrated that the kink effect is directly correlated to shallow traps…

Impact of spacing between array elements on the performances of diversity schemes in tunnels

M. Lienard, Jose-Maria Molina-Garcia-Pardo, C. Sanchis-Borras, Pierre Degauque

To increase channel capacity in tunnels, MIMO seems to be a promising technique despite the low angular spread of the rays. Indeed, for transmitting frequencies on the order or larger than 1 GHz, the tunnel behaves as an oversized waveguide and the concept of spatial diversity can be replaced by…

Magneto-electro-elastic effective properties of multilayered artificial multiferroics with arbitrary lamination direction

Stefano Giordano, Marc Goueygou, Nicolas Tiercelin, Abdelkrim Talbi, Philippe Pernod, Vladimir Preobrazhensky

This work deals with the determination of the effective response of a multilayered or laminated heterostructure composed of materials with an arbitrary coupled anisotropic behavior. In particular, we elaborate a fully algebraic technique for obtaining the homogenized parameters of a magneto-electro…

Theory and simulation of optomechanical effects in phoxonic crystals

Said El-Jallal, Mourad Oudich, Yan Pennec, Abdelkader Makhoute, Jordi Gomis-Bresco, Daniel Navarro-Urrios, Clivia M. Sotomayor Torres, Alejandro Martínez, Bahram Djafari-Rouhani

Phoxonic crystals are periodic structures that can exhibit dual phononic and photonic band gaps, thus allowing the simultaneous confinement of both acoustic and optical waves inside the same defect such as a cavity or a waveguide. Then, one can expect an enhancement of the phonon-photon interaction…
