Layered Bimetal Nanoporous Platforms for SERS Sensing
Yanqiu Zou, Anastasiia Sapunova, Tommaso Giovannini +15
Nanoporous metals are extensively investigated as platforms for applications in plasmonics. They present high surface areas and strong local electric fields that can be tuned at di…
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…
Controlled integration of MoS2 flakes on nanopores by means of electrophoretic deposition
Dario Mosconi, Andrea Jacassi, Giorgia Giovannini +7
We propose an easy and robust strategy for the versatile integration of 2D material flakes on plasmonic nanoholes by means of controlled deposition of MoS2 via electrophoretic proc…
Nanoporous gold leaves: plasmonic behavior in the visible and mid-infrared spectral regions
Denis Garoli, Gianluca Ruffato, Pierfrancesco Zilio +4
A robust and reproducible preparation of self-standing nanoporous gold leaves (NPGL) is presented, with optical characterization and plasmonic behaviour analysis. Nanoporous gold (…
Ultrafast all-optical switching enabled by epsilon-near-zero modes in metal-insulator nanocavities
Joel Kuttruff, Denis Garoli, Jonas Allerbeck +5
Ultrafast control of light-matter interactions constitutes a crucial feature in view of new technological frontiers of information processing. However, conventional optical element…
Surface Thermal Gradients Activated by Enhanced Molecular Absorption in Mid-infrared Vertical Antenna Arrays
Andrea Mancini, Valeria Giliberti, Alessandro Alabastri +4
We investigate local heat generation by molecules at the apex of polymer-embedded vertical antennas excited at resonant mid-infrared wavelengths, exploiting the surface enhanced in…
