Abstract

In recent years titanium nitride is being considered as a very promising plasmonic material for data storage applications as it exhibits a pronounced plasmonic dipolar resonance and has high thermal stability. However, there is a lack of research where higher order resonance modes are examined. We address this here by performing angle dependent spectral transmission measurements nanodisks arrays made from titanium nitride. The measurements show strong polarization dependence with s-polarized light causing excitation of the quadrupole and higher order resonance plasmonic modes. These higher order modes are required for the state-of-the-art designs of near-field transducers. This, together with its outstanding thermal properties, makes TiN a favourable material for data storage applications.
