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....

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...

Human Vision‐Adapted Semitransparent Organic Solar Cells for Multicolored Architectural Application

Zhouyi Lu, Baozhong Deng, Zhengnan Lin, Gaoyu Dai, Luqiao Yin, Gaëtan Lévêque, Bruno Grandidier, Furong Zhu, Tao Xu

Abstract Semitransparent organic solar cells (ST‐OSCs) offer significant potential for building‐integrated energy harvesting combined with daylight transmission. However, simultaneously achieving high power conversion efficiency (PCE) and perceptually accurate color rendition remains challenging....

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...
