A first outlook of sputtered FeWO₄ thin films for micro-supercapacitor electrodes

Gaëtan Buvat, Antonella Iadecola, Florent Blanchard, Thierry Brousse, Pascal Roussel, C. Lethien

The next generation of Internet of Things devices requires micro-supercapacitors operating at high voltage which is difficult to achieve using symmetrical design. Thus, their fabrication in an asymmetric configuration is mandatory. While MnO2 is well-established as positive electrode, the scarcity...

Bias-dependent intrinsic rf thermal noise modeling and characterization of single-layer graphene fets

N. Mavredakis, A. Pacheco-Sanchez, P. Sakalas, W. Wei, Emiliano Pallecchi, Henri Happy, D. Jimenez

In this article, the bias dependence of intrinsic channel thermal noise of single-layer (SL) graphene field-effect transistors (GFETs) is thoroughly investigated by experimental observations and compact modeling. The findings indicate an increase of the specific noise as drain current increases,...

DNA aptamers block the receptor binding domain at the spike protein of SARS-CoV-2

Fabrizio Cleri, Marc Lensink, Ralf Blossey

DNA aptamers are versatile molecular species obtained by the folding of short single-stranded nucleotide sequences, with highly specific recognition capabilities against proteins. Here we test the ability of DNA aptamers to interact with the spike (S-)protein of the SARS-CoV-2 viral capsid. The S-...

Wind tunnel integration of Micro-Magneto-Mechanical Systems (MMMS) microvalves for flow control experiments

Thomas Arnoult, Colin Leclercq, Cécile Ghouila-Houri, Aurélien Mazzamurro, Manon Benedito, Romain Viard, Quentin Gallas, Eric Garnier, Denis Sipp, Abdelkrim Talbi, Philippe Pernod

Flow control techniques can be defined as methods changing a flow natural dynamics. The control of a flow can be achieved with actuators affecting the flow momentum. Therefore, a MMMS microvalve was designed and characterized. The micro-actuators have then been integrated to a wind tunnel on the...

Experimental and theoretical study of group delay times and density of states in one-dimensional photonic circuit

S. Khattou, M. Amrani, A. Mouadili, E.H. El Boudouti, Abdelkrim Talbi, Abdellatif Akjouj, Bahram Djafari-Rouhani

We present a comparative study of density of states (DOS) and group delay times for a one-dimensional (1D) coaxial photonic crystal made of N cells attached horizontally along a waveguide. Using the interface response theory of continuous media, we derive exact analytical expressions relating the...

21 - Layered Photonic Crystals with Left-Handed Materials

Abdellatif Akjouj, El Houssaine El Boudouti, L. Dobrzynski, Bahram Djafari-Rouhani

We theoretically investigate the photonic band structure of layered photonic crystals composed of alternating layers of right- and left-handed materials (RHMs and LHMs). The dispersion curves are mainly studied by assuming that the dielectric permittivity and magnetic permeability are constant in...

Experimental full wavefield reconstruction and band diagram analysis in a single-phase phononic plate with internal resonators

N. Kherraz, M. Radzieński, M. Mazzotti, P. Kudela, F. Bosia, A. S. Gliozzi, D. Misseroni, N. M. Pugno, W. Ostachowicz, M. Miniaci

Research on phononic crystal architectures has produced many interesting designs in the past years, with useful wave manipulation properties. However, not all of the proposed designs can lead to convenient realizations for practical applications, and only a limited number of them have actually been...

Enhanced phonon-plasmon interaction in film-coupled dimer nanoridges mediated by surface acoustic waves

Adnane Noual, Rock Akiki, Gaëtan Lévêque, Yan Pennec, Bahram Djafari-Rouhani

The interaction between phonons and localized plasmons in coupled nanoparticles can be exploited both for modulating the scattered electromagnetic field and the understanding of the mechanical vibrations at nanoscale. In this paper, we demonstrate by numerical analysis an enhanced optomechanical...
