Photoluminescence coupled with repetitive thermal annealing has been used to study the interdiffusion process in a 10 nm GaAs 1-x Sb x /GaAs single quantum well. The diffusion equations and the Schrödinger equation were solved numerically to obtain the composition profile and the n = 1 electron to heavy-hole transition energies in the intermixed quantum well, respectively. The intermixing process was shown to obey Fick's second law. © 1998 American Institute of Physics.
