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…

Propagation of elastic waves in a one-dimensional high aspect ratio nanoridge phononic crystal phononic crystal

Abdellatif Gueddida, Yan Pennec, El Houssaine El Boudouti, George Fytas, Bahram Djafari-Rouhani

We investigate the propagation of elastic waves in a one-dimensional (1D) phononic crystal constituted by high aspect ratio epoxy nanoridges that have been deposited at the surface of a glass substrate. With the help of the finite element method (FEM), we calculate the dispersion curves of the…

Effect of MoS2 layer on the LSPR in periodic nanostructures

Mohamed El Barghouti, Abdellatif Akjouj, Abdellah Mir

Abstract In this work, we propose a new configuration of the localized surface plasmon resonance (LSPR), based on MoS2 hybrid structures for ultrasensitive biosensing applications. The plasmonic resonances are widely used in bimolecular detection and continue to be an active network because of the…

Zipping-Depinning: Dissolution of Droplets on Micropatterned Concentric Rings

José Encarnación Escobar, Erik Dietrich, S. Arscott, Harold J. W. Zandvliet, Xuehua Zhang, Detlef Lohse

The control of the surface wettability is of great interest for technological applications as well as for the fundamental understanding of surface phenomena. In this article, we describe the dissolution behavior of droplets wetting a micropatterned surface consisting of smooth concentric circular…

Nano-structured top contact with low optical polarization dependence for THz generation using photodiodes

Sara Bretin, Maximilien Billet, Emilien Peytavit, Francois Vaurette, Christophe Coinon, X. Wallart, Jean-Francois Lampin, Malek Zegaoui, Guillaume Ducournau, Mohammed Zaknoune

Uni-travelling carrier photodiode (UTC-PD) with different top optical and electrical accesses are proposed towards optical polarization sensitivity reduction. With the optimized structure, only 1 percent dependence in optical polarization is obtained while ensuring good RF access. Measurements up…

A comparative preprocessing study for softcast video transmission

Anthony Trioux, François-Xavier Coudoux, Patrick Corlay, M Gharbi

An original wireless video transmission scheme called SoftCast has been recently proposed to deal with the issues encountered in conventional wireless video broadcasting systems such as cliff effect. In this paper, we first review the SoftCast scheme. We then analyze and compare two simple…

Controlled modification of electrochemical microsystems with polyethylenimine/reduced graphene oxide using electrophoretic deposition: Sensing of dopamine levels in meat samples

Karima Kahlouche, Roxana Jijie, Ioana Hosu, Alexandre Barras, Reda Yahiaoui, Tijani Gharbi, Guillaume Herlem, Ferhat Marhoun, Sabine Szunerits, Rabah Boukherroub

Microsystems play an important role in many biological and environmental applications. The integration of electrical interfaces into such miniaturized systems provides new opportunities for electrochemical sensing where high sensitivity and selectivity towards the analyte are requested. This can be…

Resolving the Controversial Existence of Silicene and Germanene Nanosheets Grown on Graphite

Wenbing Peng, Tao Xu, Pascale Diener, Louis Biadala, Maxime Berthe, Xiaodong Pi, Yves Borensztein, Alberto Curcella, Romain Bernard, Geoffroy Prévot, B. Grandidier

The highly oriented pyrolytic graphite (HOPG) surface, consisting of a dangling bond-free lattice, is regarded as a potential substrate for van der Waals heteroepitaxy of two-dimensional layered materials. In this work, the growth of silicon and germanium on HOPG is investigated with scanning…
