Zinc oxide nanowires: Hydrothermal synthesis, and structural, electrical, and piezoelectric characterizations

Imen Ben Khaled, Elhadj Dogheche, Philippe Leclère

Zinc oxide (ZnO) nanowires (NWs) are attractive lead-free piezoelectric nanomaterials with wide range of applications. In this work, vertically aligned ZnO NWs were synthesized on sputtered ZnO seed layers via a hydrothermal process. We investigated the effects of seed layer and NWs synthesis…

Passive Monitoring Approaches for Rail Structural Health Assessment, Approches de surveillance passive pour l’évaluation de l’état de santé structurel des rails

Elissa Akiki

Structural Health Monitoring (SHM) based on ultrasonic guided waves has emerged as a promising solution for the continuous monitoring of railway infrastructures. However, most conventional SHM systems rely on active interrogation schemes requiring external excitation sources, synchronization…, La surveillance de l’état structural (SHM) basée sur les ondes guidées ultrasonores constitue une approche prometteuse pour le suivi continu des infrastructures ferroviaires. Toutefois, les systèmes conventionnels de SHM reposent majoritairement sur des méthodes actives nécessitant des sources d’…

N-polar AlGaN HEMTs on silicon for reduced contact resistance

A. Barbier-Cueil, J. Mehta, A. Pédèches, F. Medjdoub, F. Semond

Nitrogen-polar (N-polar) AlGaN-channel high electron mobility transistors (HEMTs) offer a promising pathway to overcome the limitations of equivalent metal-polar (M-polar) devices, particularly the high contact resistance associated with increased aluminum content. In this work, we report the…

A self-consistent field–matter approach for pump–probe measurements in ultrafast materials

M. Rimbert, Q. Fornasiero, J.-F. Lampin, M. Conforti, E. Peytavit

Quantitative interpretation of ultrafast pump–probe experiments requires a consistent treatment of the excitation stage, particularly under strong optical pumping where absorption saturation and interference effects become significant. We present a time-domain self-consistent framework that couples…
