In0.8Al0.2P is a III-V compound semiconductor alloy formed by substituting aluminum into indium phosphide (InP), creating a direct-bandgap material intermediate between InP and AlP. This material is primarily of research and development interest for optoelectronic and high-frequency electronic devices, where lattice-matched or near-lattice-matched heterostructures with InP substrates are desirable; it finds niche use in specialized quantum well lasers, photodetectors, and high-electron-mobility transistors (HEMTs) where the modified bandgap and bandoffset enable performance tuning compared to binary InP.
