Refractive Index of GaP, Gallium Phosphide
Gallium phosphide (GaP), a phosphide of gallium, is a compound semiconductor material with an indirect band gap of 2.26 eV. The polycrystalline material has the appearance of pale orange pieces.
For a typical sample of GaP the refractive index and extinction coefficient at 632.8 nm are 3.314 and 0.000. Below are files of complete refractive index and extinction coefficients. If the file is not available for download, you can request our proprietary file by clicking "Request".
