Tlek Tapani, Jonas M. Pettersson, Nils Henriksson +9
Nanoporous metals have emerged as promising functional architectures due to their tunable optical and electronic properties, high surface areas, and versatile use in real-life appl…
UV-SERS monitoring of plasmons photodegradation of biomolecules on Aluminum platforms decorated with Rhodium nanoparticles
Yanqiu Zou, Luca Mattarozzi, Huaizhou Jin +13
In the search for novel nanostructured materials for UV plasmonics a limited number of choices can be done. Materials such as aluminum, rhodium, gallium and few others can be used.…
Light-matter interactions in layered materials and heterostructures: from moiré physics and magneto-optical effects to ultrafast dynamics and hybrid meta-photonics
Luca Sortino, Marcos H. D. Guimarães, Alejandro Molina-Sánchez +3
Layered two-dimensional (2D) materials have revolutionized how we approach light-matter interactions, offering unprecedented optical and electronic properties with the potential fo…
Anomalous frequency scaling of acoustic phonon damping in nickel cavities fabricated by ps-laser delamination
Alba Viejo-Rodríguez, Andrea Rossetti, Marco Gandolfi +9
Single-shot picosecond (ps) laser induced delamination allows for the direct generation of suspended membranes from a continuous metallic film, offering a promising platform for co…
Copper-based disordered plasmonic system with dense nanoisland morphology
Tlek Tapani, Roman Krahne, Vincenzo Caligiuri +14
Dry synthesis is a highly versatile method for the fabrication of nanoporous metal films, since it enables easy and reproducible deposition of single or multi-layer(s) of nanostruc…
