SUMMARY

This discussion focuses on obtaining refractive index versus wavelength data for Gallium Antimonide (GaSb) and Indium Antimonide (InSb) in the wavelength range of 2μm to 20μm. The user has identified two primary sources, refractiveindex.info and Ioffe Institute, which only provide data up to 1-2μm. The user seeks additional resources for longer wavelengths and references a specific article on ResearchGate that may contain relevant optical properties data.

PREREQUISITES
  • Understanding of refractive index and its significance in optics.
  • Familiarity with materials science, specifically semiconductor materials like GaSb and InSb.
  • Knowledge of optical properties and measurement techniques.
  • Ability to navigate academic resources and databases for scientific literature.
NEXT STEPS
  • Research the optical properties of GaSb and InSb in the 2μm to 20μm range.
  • Explore additional academic articles on ResearchGate related to semiconductor optical properties.
  • Investigate databases that specialize in material properties, such as the Materials Project.
  • Learn about the methods for calculating refractive indices for semiconductors under varying conditions.
USEFUL FOR

Researchers, materials scientists, and optical engineers seeking detailed refractive index data for GaSb and InSb, particularly in the infrared wavelength range.

I need to obtain refractive index vs wavelength data for the following materials:

GaSb (Gallium Antimonide)
InSb (Indium Antimonide)

For the range from 2μm up to ideally 20μm but up to 10μm would do.

Looking on the two websites I know of for sourcing such data:

http://refractiveindex.info/?shelf=main&book=GaSb&page=Aspnes
http://www.ioffe.ru/SVA/NSM/nk/A3B5/Gif/gasb.gif

But these websites only have values up to 1-2μm.

Where can I find data for larger wavelengths?
