Low-loss plasmonic metamaterial based on epitaxial gold monocrystal film

We demonstrate high-finesse plasmonic metamaterial with strong resonant response in the near-IR spectral range fabricated using a thin low-loss film of gold monocrystal. The monocrystal was grown using specially formulated simplified crystal growth procedure based on epitaxial deposition, which makes it readily accessible to both plasmonics and metamaterials communities.
