WebMay 1, 2003 · The use of pure InGaAs as barrier material is expected to give a small electron confinement and a poor high-temperature performance, whereas a barrier material of pure InAlAs would result in a lower change in the refractive index with respect to InP. Therefore In x Al y Ga 1−x−y As is preferred as barrier material, as compared to the ternaries.
