Deposited ultra-thin titanium nitride nanorod array as a plasmonic near-perfect light absorber
Abstract The transmittance, reflectance, and extinctance that correspond to the localized plasmonic resonance within TiN nanorods were investigated. The obliquely deposited TiN nanorod array shows polarization-independent admittance matching to air. Unlike noble metal nanorods, the near-field locali...
