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...

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....

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...
