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.…

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…

The impact of defect density on a CGS/CIGS tandem solar cell’s performance

D. Achouri, A. Aissat, S. Dupont, M.H. Dhaou, F. Saidi, J.-P. Vilcot

Copper Indium Gallium Selenide (CIGS) solar cells became a leading thin-film photovoltaic device because of their stability, relatively low production costs, and high efficiency, particularly when used in tandem configurations. A monolithic tandem cell is proposed in this paper. Copper Gallium…
