In Situ Multiscale Investigation of Capillary-Force-Induced Cold-Welding of Silver Nanowire Networks

Yevheniia Chernukha, Laetitia Bardet, Maxime Berthe, Thomas Lerond, Jean-Paul Mazellier, Laurent Gangloff, Aurore Denneulin, Pascale Diener, Daniel Bellet

Silver nanowire (AgNW) networks are in the spotlight as flexible transparent electrodes (TEs) thanks to their combination of high optical transmittance, low electrical resistance, and excellent flexibility. As such network is formed from a multitude of interwoven AgNW, a postdeposition treatment is…

Quantitative calibration of a TWPA applied to an optomechanical platform

Alexandre Delattre, Ilya Golokolenov, Richard Pedurand, Nicolas Roch, Arpit Ranadive, Martina Esposito, Luca Planat, Andrew Fefferman, Eddy Collin, Xin Zhou, Mika A Sillanpää, Laure Mercier de Lépinay, Andrew D Armour, Jonas Glatthard

In the last decade, the microwave quantum electronics toolbox has been enriched with quantumlimited detection devices such as Traveling Wave Parametric Amplifiers (TWPAs). The extreme sensitivity they provide is not only mandatory for some physics applications within quantum information processing…

Experimental demonstration of tunable spectral flow of elastic localized modes

Sai Aditya Raman Kuchibhatla, Aakash Gupta, Marco Miniaci, Michael Leamy

We experimentally demonstrate the tunability of a topological defect mode and its spectral flow within the bandgap of a periodic structure made of beams and cylindrical masses and hosting a topological bandgap in its frequency spectrum. A defect is introduced by incorporating a pair of…

Remarkable electronic and optical properties of HgTe quantum dots

Antoine Hage, Christophe Delerue

HgTe is a very special material. Semi-metallic in bulk, it can become semiconducting under the effect of quantum confinement. This is well known in the case of quantum wells based on HgCdTe/HgTe/HgCdTe heterostructures with infrared optoelectronic properties at the heart of current applications.…

Digital Predistortion of D-Band Power Amplifiers Using AI-Based Nonlinearity Compensation

Hiba Alqasir, Justine Mauro, Ihsen Alouani, Iyad Dayoub

This paper presents the first demonstration of a neural network-based digital predistortion (DPD) architecture for compensating nonlinearities in real D-band power amplifiers (PAs). The proposed method employs two separate models to independently correct amplitude (AM/AM) and phase (AM/PM)…

Sierpiński carpet-inspired hierarchical patterning of porous materials for sound absorption

S. Kuznetsova, F. Allein, V.F. Dal Poggetto, F-X Bécot, M Miniaci

Efficient sound absorption at low and mid frequencies is essential for mitigating anthropogenic noise but remains a scientific and engineering challenge. While porous materials are effective at medium and high frequencies, they typically require considerable thickness to absorb low-frequency sound…
