Refractive Index of Al90Ga10As
Aluminium gallium arsenide (also aluminum gallium arsenide) (AlxGa1-xAs) is a semiconductor material with very nearly the same lattice constant as GaAs, but a larger bandgap. The x in the formula above is a number between 0 and 1 - this indicates an arbitrary alloy between GaAs and AlAs.
For a typical sample of Al90Ga10As the refractive index and extinction coefficient at 632.8 nm are 3.206 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".
