High voltage excitation and nonlinear transmission of a 16 MHz AlN-based piezoelectric micro-machined ultrasonic transducer

Wen-Juan Liu

This paper reports a 16 MHz AlN-based piezoelectric micro-machined ultrasonic transducer (PMUT) under high voltage excitation. The proposed PMUT array consists of 44x39 elements fabricated on a silicon-on-insulator (SOI) substrate with 1 μm AlN film on 5 μm silicon membrane. The electrical…

Binary sessile drops evaporation: IR and acoustic methods for alcohol concentration tracking at the interface and the surface

Pin Chen, Malika Toubal, Julien Carlier, Souad Harmand, Bertrand Nongaillard, Maxence Bigerelle

Evaporation process of droplets of three pure liquids (water, 1-butanol, and ethanol) and four binary solutions (5 wt % 1-butanol water-based solution and 5, 25, and 50 wt % ethanol−water-based solutions) deposited on hydrophobic silicon substrate was studied under ambient condition. An optical…

Dual sensing and actuation of ultrathin conducting polymer transducers

Tan Ngoc Nguyen, Cedric Plesse, Frederic Vidal, Sébastien Grondel, Eric Cattan, John D.W. Madden

Conducting polymers are active materials that exhibit an interesting bidirectional electromechanical coupling, where an input voltage results in the displacement of the film and a voltage is produced when a displacement is applied to the film. Mechanical deformation of the transducer by external…

Elaboration of nanomagnet arrays: organization and magnetic properties of mass-selected FePt nanoparticles deposited on epitaxially grown graphene on Ir(111)

Pierre Capiod, Laurent Bardotti, Alexandre Tamion, Olivier Boisron, Clément Albin, Veronique Dupuis, Gilles Renaud, Philippe Ohresser, Florent Tournus

The moiré pattern created by the epitaxy of a graphene sheet on an iridium substrate can be used as a template for the growth of 2D atomic or cluster arrays. We observed for the first time a coherent organization of hard magnetic preformed FePt nanoparticles on the 2D lattice of graphene/Ir(111).…

Rainbow guiding of the lowest-order antisymmetric Lamb mode in phononic crystal plate

Jinfeng Zhao, Weitao Yuan, Bernard Bonello, Bahram Djafari-Rouhani, Yongdong P Pan, Zheng Zhong

The modern acoustic circuits have experienced significant progress with the development of artificial structures, including phononic crystals, metamaterials or metasurfaces. Among the most intensive topics, the reconfigurable acoustic guides are achieved through several mechanisms. In this work, we…

“Click” Chemistry on Gold Electrodes Modified with Reduced Graphene Oxide by Electrophoretic Deposition

Vladyslav Mishyn, Patrik Aspermair, Yann R. Leroux, Henri Happy, Wolfgang Knoll, Rabah Boukherroub, Sabine Szunerits

The coating of electrical interfaces with reduced graphene oxide (rGO) films and their subsequent chemical modification are essential steps in the fabrication of graphene-based sensing platforms. In this work, electrophoretic deposition (EPD) of graphene oxide at 2.5 V for 300 s followed by vapor…

Micro air vehicle to nano air vehicle : theoretical and experimental studies of an artificial flapping insect, Du micro véhicule aérien au nano véhicule aérien : études théoriques et expérimentales sur un insecte artificiel à ailes battantes

Le Anh Doan

In recent decades, the prospect of exploiting the exceptional flying capacities of insects has prompted much research on the elaboration of flapping-wing nano air vehicles (FWNAV). However, when designing such a prototype, designers have to wade through a vast array of design solutions that…, Au cours des dernières décennies, la possibilité d’exploiter les capacités de vol exceptionnelles des insectes a été à l’origine de nombreuses recherches sur l’élaboration de nano-véhicules aériens (NAVs) à ailes battantes. Cependant, lors de la conception de tels prototypes, les chercheurs doivent…

High Efficiency AlN/GaN HEMTs for Q-Band Applications with an Improved Thermal Dissipation

Riad Kabouche, Romain Pecheux, Kathia Harrouche, Etienne Okada, F Medjdoub, Joff Derluyn, Stefan Degroote, Marianne Germain, Filip Gucmann, Callum Middleton, James W Pomeroy, Martin Kuball

In this paper, we demonstrate Q-band power performance of carbon doped AlN/GaN high electron mobility transistors (HEMTs) using a deep sub-micrometer gate length (120 nm). With a maximum drain current density ID of 1.5 A/mm associated to a high electron confinement and an extrinsic transconductance…
