Title: Plasmonic spectral tunability of conductive ternary nitrides

Abstract

Conductive binary transition metal nitrides, such as TiN and ZrN, have emerged as a category of promising alternative plasmonic materials. In this work, we show that ternary transition metal nitrides such as Ti{sub x}Ta{sub 1−x}N, Ti{sub x}Zr{sub 1−x}N, Ti{sub x}Al{sub 1−x}N, and Zr{sub x}Ta{sub 1−x}N share the important plasmonic features with their binary counterparts, while having the additional asset of the exceptional spectral tunability in the entire visible (400–700 nm) and UVA (315–400 nm) spectral ranges depending on their net valence electrons. In particular, we demonstrate that such ternary nitrides can exhibit maximum field enhancement factors comparable with gold in the aforementioned broadband range. We also critically evaluate the structural features that affect the quality factor of the plasmon resonance and we provide rules of thumb for the selection and growth of materials for nitride plasmonics.

  • Single nanoantenna spectroscopy was carried out on realistic dipole nanoantennas with various arm lengths and gap sizes fabricated by electron-beam lithography. A significant difference in resonance wavelength between realistic and ideal nanoantennas was found by comparing their spectral response. Consequently, the spectral tunability (96 nm) of the structures was significantly lower than that of simulated ideal nanoantennas. These observations, attributed to the nanofabrication process, are related to imperfections in the geometry, added metal adhesion layer, and shape modifications, which are analyzed in this work. Our results provide important information for the design of dipole nanoantennas clarifying the role of the structuralmore » modifications on the resonance spectra, as supported by calculations.« less
  • Clusters of plasmonic nanoparticles and nanostructures support Fano resonances. Here we show that this spectral feature, produced by the interference between bright and dark modes of the nanoparticle cluster, is strongly dependent upon both geometry and local dielectric environment. This permits a highly sensitive tunability of the Fano dip in both wavelength and amplitude by varying cluster dimensions, geometry, and relative size of the individual nanocluster components. Plasmonic nanoclusters show an unprecedented sensitivity to dielectric environment with a local surface plasmon resonance figure of merit of 5.7, the highest yet reported for localized surface plasmon resonance sensing in a finitemore » nanostructure.« less
  • The ability to manipulate plasma waves in the two-dimensional-(2D)-electron-gas based plasmonic crystals is investigated in this work. It is demonstrated that the plasmon resonance of 2D plasmonic crystal can be tuned easily at terahertz frequency due to the wavevector quantization induced by the size effect. After calculating self-consistently by taking into account several potential mechanisms for the resonant damping of plasma waves, it can be concluded that the plasmon-plasmon scattering plays the dominant role. Based on the calculations, we can predict the scattering or inter-excitation among the oblique plasmons in the 2D crystal. The results can be extended to studymore » 2D-electron-gas plasmonic waveguides, terahertz modulators, and detectors with electrostatic gating.« less
