## Title

- title: Optimizing the Optical Response of Uniaxial Cerium Hexaboride Films for High-Temperature
    Plasmonic Applications
  title_type: original
  lang: en

## Description

- description: Refractory materials with good optical properties are required for
    the development of novel high-temperature photonic and plasmonic photothermal
    applications. Whereas conventional plasmonic materials have excellent optical
    properties but low melting points, most refractory metals exhibit low plasmonic
    responses and oxidize easily in the atmosphere. Hence, in this study, cerium hexaboride
    (CeB6) thin films are grown via electron-beam deposition on Si(100) and sapphire
    substrates. Epitaxial growth of this material is achieved under specific conditions,
    thus yielding high crystallinity and strong plasmonic polarizability within the
    infrared spectral region. The optical properties of CeB6 improved significantly
    depending on the template substrate and growth conditions, achieving a six times
    higher plasmonic figure-of-merit on R-sapphire compared with on Si substrates.
    The high performance of CeB6 films, as reflected by their superior plasmonic figures-of-merit
    particularly in the near-infrared region (1.0–2.0 μm) compared with conventional
    refractory materials, renders them highly promising candidates for photothermal
    and optoelectronic applications.
