AuAg Alloy Permittivity and Fano-Resonant Nanostructure Measurements

Ellipsometric data for gold-silver alloys fabricated via a low-temperature annealing technique, along with measurements and calculations of single-structure alloyed Fano-resonance nanostructures. The data accompanies the manuscript "Low temperature annealing method for fabricating alloy nanostructures and metasurfaces: Unlocking a novel degree of freedom" (arXiv:2105.02461) by Debdatta Ray of École Polytechnique Fédérale de Lausanne. The dataset includes permittivity values from the Rioux model and corresponding structural calculations.

Use Cases

• Modeling optical properties of alloy nanostructures based on provided permittivity data.
• Designing Fano-resonant metasurfaces using the measured response of the 4-rod nanostructures.
• Validating computational models for alloy permittivity against the provided ellipsometric measurements.
• Investigating the effects of low-temperature annealing on the optical constants of AuAg alloys.

Strengths

• Data is directly linked to a peer-reviewed manuscript (arXiv:2105.02461), providing academic context.
• Includes both measured ellipsometric data and calculated results for Fano-resonant structures.
• Files are accompanied by detailed Readme files explaining the contents.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
