Co-integrated microfluidic and THz functions for biochip devices

Simon Laurette, A. Treizebre, Bertrand Bocquet

TeraHertz (THz) spectroscopy is becoming an alternative way to probe biological interactions in real-time conditions. However, accurate and reproducible THz measurements of aqueous solutions, largely represented in life sciences, remain difficult. A THz microsystem which couples both...

Giant magnetostrictive nanostructured films with auto induced spin reorientation transition

Yannick Dusch, Nicolas Tiercelin, A. Klimov, V. Rudenko, Y. Ignatov, S. Hage-Ali, Philippe Pernod, Vladimir Preobrazhensky

In various micro and nanosystems applications comprising magnetic films, the polarizing field still needs to be integrated. We hereby present a solution for self biasing of magnetic films using micropatterned permanent magnets. Micromagnetic simulations were used as a designing and optimization...

Magnetoelectric memory using perpendicular magnetization states and magnetoelastic switching

Nicolas Tiercelin, Yannick Dusch, V.L. Preobrazhensky, Philippe Pernod

We present here a concept of a memory cell called MELRAM based on a magnetic element with giant magnetostriction, embedded in a piezoelectric matrix. Two equilibrium orientations of magnetization are defined by combining uniaxial anisotropy together with a magnetic polarization in the hard axis...

High frequency ultrasound, a tool for elastic properties measurement of thin films fabricated on silicon

Pierre Campistron, Julien Carlier, N. Saad, J. Gao, Malika Toubal, L. Dupont, Georges Nassar, Bertrand Nongaillard

The main goal of this work is to develop an ultrasonic high frequency measurement method for the characterization of thin layers. The development of high frequency acoustic transducers for longitudinal waves and shear waves on silicon has made it possible to develop characterization of thin films...

Asymmetry of polarization reversal and current-voltage characteristics of Pt/PZT-Film/Pt:Ti/SiO2/Si-substrate structures

S.L. Bravina, N.V. Morozovsky, J. Costecalde, Caroline Soyer, Denis Remiens, D. Deresmes

The characterization of the asymmetries of bipolar charge-voltage and current-voltage loops of polarization reversal and unipolar current-voltage curves for Pt/PZT-film/Pt:Ti/SiO2/Si-substrate systems was performed in the dynamic mode. The asymmetry of local deformation-voltage loops was observed...

Low-noise microwave performance of AlN/GaN HEMTs grown on silicon substrate

F Medjdoub, Nicolas Waldhoff, Malek Zegaoui, B. Grimbert, N. Rolland, Paul-Alain Rolland

Microwave noise performance of state-of-the-art AlN/GaN high-electron-mobility transistors (HEMTs) grown on 100-mm Si substrate has been investigated. DC and RF measurements show the outstanding potential of this structure for high-power millimeter-wave (mmW) applications. A maximum output current...

Highly coherent terahertz wave generation with a dual-frequency Brillouin fiber laser and a 1.55 μm photomixer

Guillaume Ducournau, P. Szriftgiser, Tahsin Akalin, Alexandre Beck, Denis Bacquet, Emilien Peytavit, Jean-Francois Lampin

Thanks to a portable dual-frequency Brillouin fiber laser and a 1.55 μm photomixer, we report the generation of a highly coherent kilohertz level submillimeter wave emission. Low-cost telecommunications components are used to achieve very simple source architecture. The photomixer is composed of a...

Thickness effect on nanoscale electromechanical activity in Pb(Mg1/3Nb2/3)O3-PbTiO3 thin films studied by piezoresponse force microscopy

A. Ferri, M. Detalle, J.F. Blach, M. Warenghem, Denis Remiens, R. Desfeux

0.7Pb(Mg1/3Nb2/3)O3–0.3PbTiO3 (PMN–PT) ferroelectric thin films with thickness ranging from 28 to 110 nm were sputter deposited onto LaNiO3/SiO2/Si substrates. Optical properties were determined by spectroscopic ellipsometry. We found B = 4.6 and λ0 = 209 nm, which is consistent for all PMN–PT...
