Thermally Robust Plasmonic Nanorings from Titanium Nitride.

ABSTRACT: Plasmonic nanostructures are widely utilized in fields such as chemical sensing, photothermal therapy, and optoelectronics due to their ability to confine and enhance electromagnetic fields at the nanoscale. Among these, nanorings offer unique advantages owing to their hollow-core geometry, which supports multiple plasmonic modes and enables efficient analyte access. However, conventional plasmonic materials such as gold, silver, or copper suffer from poor thermal stability due to either oxidation or morphological degradation, rendering them unsuitable for high temperatures or chemically harsh environments. In this study, we investigate titanium nitride (TiN) as a robust alternative for the fabrication of thermally stable plasmonic nanorings. TiN combines metallic optical behavior in the v
