Intermixing in an undoped InGaAsP/InP quantum well structure enhanced by near-surface defects generated using inductively coupled argon plasma is temperature dependent. The group III sublattice interdiffusion can be four times as fast as that of the group V sublattice for the annealing temperature lower than 600 °C, and a maximum band gap redshift of 50 nm is obtained in experiment. Blueshift is obtained at 700 °C when the group V sublattice interdiffusion becomes appreciable.
