摘要：

Data are presented showing that the interdiffusion of Ga and Al (AlGaAs-GaAs) and of Ga and In (pseudomorphic InGaAs-GaAs) at a heterojunction can be significantly enhanced or suppressed by controlling group III vacancies and interstitials. High-resistivity low-temperature GaAs which contains excess As is shown to accelerate the interdiffusion process. The emission wavelength from monolayer-thick quantum wells can remain relatively unchanged even after annealing for 200 h at 850-degrees-C.
