Material-specific mapping of plasmonic modal dispersion via discrete momentum-space probes

Youssef El Badri, Hicham Mangach, Yan Pennec, Bahram Djafari-Rouhani, Abdenbi Bouzid, Mustapha Bahich, Younes Achaoui

Abstract Accurate measurement of surface plasmon polariton (SPP) dispersion remains challenging, as conventional angle-resolved techniques are limited by surface quality, diffraction artifacts, and geometry-induced band folding. Here, we show that SPP dispersion can be reconstructed from…

Out-of-Plane Transport and Thermal Properties of an Organic Charge-Transfer Thin Film and Their Donor/Acceptor Constituents.

Maria Elisabetta Giglio, Alexandra Harbuzaru, L. Thomas, Dominique Vuillaume, Marta Mas-Torrent

Vertical charge injection and out-of-plane heat transport are central to organic electronic materials, yet remain largely unexplored in solution-processed thin films of donor-acceptor charge-transfer systems. Here, we investigate Ph-BTBT-C10, F4TCNQ, and their 1:1 charge-transfer complex (CTC) by…

Optimisation de transducteurs ultrasonores hautes fréquences à base de ZnO pour applications MEMS, Optimization of high-frequency ZnO-based ultrasonic transducers for MEMS applications

Reda Aitayad

Ce manuscrit porte sur la fabrication et l’optimisation de transducteurs à ondes acoustiques de volume (BAW) à base de couches minces de ZnO. L’optimisation concerne d’abord le matériau piézoélectrique en couche mince : le dépôt du ZnO par pulvérisation cathodique RF est optimisé, et la condition…, This manuscript focuses on the fabrication and optimization of bulk acoustic wave (BAW) transducers based on ZnO thin films. The optimization first concerns the piezoelectric thin-film material: ZnO deposition by RF magnetron sputtering is optimized, and the 80% Ar / 20% O₂ condition makes it…
