Thin-film adhesion characterization by Colored Picosecond Acoustics

Arnaud Devos, P. Emery

This paper presents some applications of a recent technique so-called the Colored Picosecond Acoustics (APiC) to the characterization of complex stacks of thin films. The technique is a unique combination of optics and acoustics that implements an acoustic pulse-echo technique at the nanoscale…

Magnetoplasmonic nanograting geometry enables optical nonreciprocity sign control

L. Halagačka, Mathias Vanwolleghem, Francois Vaurette, J. Ben Youssef, K. Postava, J. Pištora, Béatrice Dagens

We experimentally demonstrate a disruptive approach to control magnetooptical nonreciprocal effects. It has been known that the combination of a magneto-optically (MO) active substrate and extraordinary transmission (EOT) effects through deep-subwavelength nanoslits of a noble metal grating, leads…

Effective and rapid technique for temporal response modeling of surface acoustic wave interdigital transducers

Dame Fall, Marc Duquennoy, Mohammadi Ouaftouh, Bogdan Piwakowski, Frédéric Jenot

Surface Acoustic Wave Interdigital Transducers (SAW-IDT) has a considerable application potential for characterization of properties of thin layers, coatings and functional surfaces. For optimization of these SAW-IDTs, it is necessary to study various SAW-IDT configurations by varying the number of…

A time-domain model and experimental validation of the acoustic field radiated by air-coupled transducers

Ji Li, Bogdan Piwakowski

This paper presents a time-domain model for the prediction of an acoustic field in an air-coupled, noncontact, ultrasonic setup, which includes an air-coupled Emitter, the Propagation space and an aircoupled Receiver (EPR). The model takes into account the finite size of the aperture receiver,…

Measurement of the thermal conductivity of flexible biosourced polymers using the 3-omega method

Ghizlane Boussatour, Pierre-Yves Cresson, Benoit Genestie, Nicolas Joly, Jean-François Brun, T. Lasri

The thermal conductivity of flexible biosourced polymers was measured by the 3-omega method. Two biopolymers were investigated: the polylactic acid (PLA), a widely used commercial biodegradable one, and the cellulose palmitate (CP), a hydrophobic biosourced material developed in the laboratory,…

Non-destructive characterization of surfaces and thin coatings using a large-bandwidth interdigital transducer

Dame Fall, Marc Duquennoy, Mohammadi Ouaftouh, Nikolay Smagin, Bogdan Piwakowski, Frédéric Jenot

This paper deals with non-destructive testing of thin layer structures using Rayleigh-type waves over a broad frequency range (25-125 MHz). The dispersion phenomenon was used to characterize a layer-on-substrate-type sample comprising a thin layer of platinum 100 nm thick on a silicon substrate.…

Electronic Biosensing with Flexible Organic Transistor Devices

Caroline Kotlowski, Patrik Aspermair, Hadayat Ullah Khan, Ciril Reiner-Rozman, Josef Breu, Sabine Szunerits, Jang-Joo Kim, Zhenan Bao, Christoph Kleber, Paolo Pelosi, Wolfgang Knoll

In this short review, we summarize the design and implementation of organic semiconducting materials-based field-effect transistors (OFETs) and the fabrication and use of reduced graphene-oxide field-effect transistors (rGO–FETs) as flexible transducers for electronic biosensing. We demonstrate…
