Notes:
On quaternary/quaternary multiple quantum wells, with constant P/As ratio and In-rich wells, we show the possibility of producing a blueshift of the heavy hole exciton line with interdiffusing only group III atoms, similarly to GaAs/GaAlAs and InGaAs/GaAs systems. This kind of structure, particularly suitable for group III diffusion study, has allowed us to obtain a quantitative value of the In–Ga interdiffusion coefficient at 850 °C: DIn–Ga≈4.72×10−16 cm2 s−1. © 1995 American Institute of Physics.
