Abstract

This comparative study investigates the refractive index sensitivity of gold (Au), titanium nitride (TiN), and hafnium nitride (HfN) nanodisk arrays in exciting surface lattice resonances and localized plasmon resonance modes. The plasmonic nanodisk arrays are fabricated using electron beam lithography and optimized for disk diameter and array period. This work provides valuable insights into the comparative performance of TiN, HfN, and Au nanodisk arrays for refractive sensing-based applications.
