Competing regimes of charge-carrier and impurity scattering limiting phonon heat conduction in heavily-doped silicon

Raja Sen, Juan Carlos Acosta Abanto, Mélanie Brouillard, Séverine Gomès, Jean-François Robillard, Alessandro Ciavatta, Lorenzo Paulatto, Nathalie Vast, Jérôme Saint-Martin, Jelena Sjakste, Pierre-Olivier Chapuis

With respect to undoped semiconductors, thermal transport by phonons is limited by two additional mechanisms when doping increases: charge-carrier and impurity scattering. Previous works provided contradicting conclusions on the dominant doping-induced scattering mechanism in silicon. In this work,…

Vibration and sound of two padel rackets compared in playing conditions

Thomas Daney, Delphine Chadefaux, Jean-Loïc Le Carrou, Arthur Paté

In an attempt to better understand the vibratory and acoustic aspects of ball/racket impact as experienced by padel players, an experimental investigation was carried out with the aim of comparing the vibration and sound produced by a ball impacting two different padel rackets. These two rackets…

Photonic Klein Tunnelling in Silicon Topological Materials for Terahertz 6G Interconnects

Samina Mulla, Sangram Kumar Sadhu, Siddhartha Lal, Anshuman Kumar, N S Vidhyadhiraja, Zhonghua Gu, Prakash Pitchappa, Pascal Szriftgiser, Guillaume Ducournau, Abhishek Kumar

<div><p>Topological photonics enables robust light transport along engineered interfaces, but transport across a potential barrier placed within such an interface, and the range of barrier strengths over which it survives, remain largely unexplored. Here we experimentally demonstrate…

Enhancement of perpendicular magnetic anisotropy and Dzyaloshinskii-Moriya interaction in cobalt-based systems through interfacial engineering

M. Belmeguenai, T. Al Maawali, A. Bendjaballah, W. Fotso, M. G. Hafiz, M. Ramu, S. M. Chérif, N. Tiercelin, M. S. Gabor, Y. Roussigné, S. N. Piramanayagam, R. Sbiaa

Interfacial engineering provides an effective route to tailor chiral magnetic interactions in thin-film heterostructures relevant for spintronic applications. In this work, we investigate the influence of top capping layers on perpendicular magnetic anisotropy (PMA) and interfacial Dzyaloshinskii…

Localized phonon-polaritons in natural mineral particles extend to atmospheric scales

Jeyan Bichon, Hervé Herbin, J-F Lampin, D Petitprez, Romain Peretti, S Eliet-Barois

Localized phonon-polaritons confine electromagnetic fields to subwavelength dimensions and are widely studied in engineered photonic structures. Whether this light-matter physics can arise intrinsically in naturally occurring, free-standing solid particles has remained unexplored. Here we show that…

Spatiotemporal terahertz emission nanoscopy of spintronic photocurrent

Felix Paries, Reza Rouzegar, Jiahua Cai, Mingcong Dai, Felix Selz, Johanna Koelbel, Geoffrey Lezier, Nicolas Tiercelin, Daniel Molter, Daniel M Mittleman, Georg von Freymann, Xiaojun Wu, Tom S Seifert

Capturing ultrafast spin and charge photocurrents on nanoscopic scales is essential for fundamental research in physics and engineering, as well as for future applications, such as novel spin-orbitronic devices. Accessing the fundamental dynamics driven by changes in electronic energy, linear…

A trick of the tail: how electrostatics helps a DNA repair enzyme to localize on nucleosomes

Safwen Ghediri, Guillaume Brysbaert, Fabrizio Cleri, Ralf Blossey

Electrostatic interactions are key to the recognition processes of proteins and DNA and have been previously documented for the action of repair enzymes. Uracil-DNA glycosylase (UDG) is the first in a sequence of enzymes that act in the base-excision repair process (BER) and whose task is the…

Storing sensor events in the interconnection strength of conducting polymer dendrites

Antoine Baron, Bilel Hafsi, Enrique H. Balaguera, Sébastien Pecqueur

If electronics drives only electrons to charge electrodes, natural systems learn by moving matter to evolve. Morphogenesis in sessile organisms can be seen both as a fabrication process and as an operative mechanism. However, intricating manufacturing and programming functionalities in electronic…

Investigating the relationship between dendrite resistance and surface carbonate content in single-ion conducting polymer electrolyte lithium metal batteries

Kyra D. Owensby, Steven Lam, Robert Sacci, Gabriel M. Veith, Wan-Yu Tsai, Ritu Sahore, Harry M. Meyer Iii, Gregory P. Carden, Michelle L. Lehmann, X. Chelsea Chen

Single-ion conducting polymer electrolytes (SIPEs) offer high cation transference numbers (tLi+ > 0.7) that suppress concentration gradients, yet their operational stability against lithium metal remains constrained by early dendritic short-circuiting. Here, we report how targeted…

Measurement of magnetic loss in ferromagnetic lamella using high sensitivity piezo-magnetic surface acoustic wave sensor

Othmane Marbouh, Gaétan Sanchez, Aurelien Mazzamurro, Mohamed Boutghatin, Olivier Bou Matar, Yannick Dusch, Romain Viard, Aymen Ammar, Philippe Pernod, Nicolas Tiercelin, Abdelmounaim Tounzi, Abdelkader Benabou, Abdelkrim Talbi

Magnetic field sensors combining surface acoustic waves (SAW) and magnetostrictive thin films have shown promising sensitivity in laboratory studies, but their translation into real-world applications has remained limited. In this work, we report the first practical deployment of a shear-horizontal…
