Gallium nitride based plasmonic multilayer operating at 1.55µm

Arnaud Stolz, Laurence Considine, Salim Faci, El Hadj Dogheche, Charlotte Tripon-Canseliet, Brigitte Loiseau, Dimitri Pavlidis, Didier Decoster, Jean Chazelas

In this Letter, we have designed and fabricated a III-V semiconductor multilayer based on surface plasmon resonance (SPR) operating at the telecom wavelength. Optimization of the optogeometrical parameters and the metal/semiconductor layers required for this novel structure was conducted accurately…

High frequency SAW-IDT MEMS sensors for ultrasonic characterization of thin films deposited on substrates

M. Duquennoy, M. Ouaftouh, J. Deboucq, Frédéric Jenot, Mohamed Ourak, Julien Carlier, Emmanuel Moulin

The use of coatings and thin films deposited on substrates is highly sought-after in many applications. The objectives of these coatings and deposits are numerous. It may be used, for example, to improve the durability of structures, including their resistance to wear and fatigue or to obtain…

Young modulus and Poisson ratio of PZT thin film by Picosecond Ultrasonics

F. Casset, A. Devos, S. Sadtler, A. Le Louarn, P. Emery, G. Le Rhun, P. Ancey, S. Fanget, E. Defay

Thin-film sol-gel Pb(Zr 0.52 , Ti 0.48 )O 3 (PZT) can be used in many actuator applications thanks to its high piezoelectric coefficients. The accurate knowledge of its mechanical properties such as Young modulus (E) and Poisson ratio (ν ν) or stiffness matrix is a key point for predictive design,…

Influence of 1-3 piezocomposite fabrications on lateral modes

Rémi Rouffaud, Anne-Christine Hladky, Maï Pham-Thi, Claire Bantignies, Franck Levassort

—Properties of 1-3 piezocomposites with periodic structure were characterized. This material can be typically fabricated in using the " dice and fill " method (DFM) and two phases were used (PMN-34.5PT ceramic and epoxy resin). The corresponding numerical simulations allowed to study the…

AlN/IDT/AlN/Sapphire as packageless structure for SAW applications in harsh environments

Ouarda Legrani, Omar Elmazria, A. Bartasyte, Thierry Aubert, Abdelkrim Talbi

Packageless heterostructure AlN/IDT/AlN/Sapphire was investigated as a solution protection of the interdigital transducer against agglomeration phenomena at high temperature. For this purpose, the performance of conventional IDT/AlN/Sapphire and protected AlN/IDT/AlN/Sapphire heterostructures were…

Reflections on Learning Mathematics in Physics Phenomenology and Historical Conceptual Streams.

Maria Mellone, Raffaele Pisano

Although several efforts produced by new mathematical education approaches for improving education systems and teaching, yet the results are not sufficient to adsorb the totality of innovations proposed, both in the contents and management. In this sense constructive debates and new ideas were…
