Copper nanowires exhibit high-quality visible-infrared plasmons, challenging previous assumptions about copper

Area of Science:

  • Plasmonics
  • Materials Science
  • Nanotechnology

Background:

  • Silver is the preferred plasmonic material due to low visible-infrared (vis-IR) absorption.
  • Copper is generally considered too lossy for plasmonic applications.
  • High-quality plasmons are crucial for advanced optical applications.

Purpose of the Study:

  • To demonstrate high-quality visible-infrared (vis-IR) plasmons in copper nanowires (NWs).
  • To investigate the factors contributing to plasmon quality in elongated nanostructures.
  • To explore the potential of copper as a viable plasmonic material.

Main Methods:

  • Electron energy-loss spectroscopy (EELS) was used to measure plasmon quality factors.
  • Comparative measurements were performed on silver and copper nanowires of varying diameters.

  • Analysis focused on radiative and nonradiative loss mechanisms across a broad spectral range.

    • Main Results:

    • Copper nanowires exhibited plasmons with quality factors exceeding 60 in the vis-IR region.
    • The electromagnetic energy of these plasmons was found to reside primarily outside the copper, reducing sensitivity to losses.
    • Low-energy modes (<20 meV) showed significant thermal population, enabling temperature determination.
    • Relative importance of radiative and nonradiative losses was elucidated for both silver and copper.

    Conclusions:

    • Copper is a viable, cost-effective material for high-quality plasmonics in elongated nanostructures.
    • The unique properties of copper nanowires open new avenues for plasmonic device development.
    • Understanding loss mechanisms is key to optimizing plasmonic performance in different materials.
