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.

对于典型的样品 - Al42Ga58As - 波长在 632.8 nm 下的折射率和消光系数为3.62277及0.03701227。 以下是包含完整折射率和消光系数的文件。 如果文件无法下载，请点击“请求”（Request）以索取该专有文件。
