Abstract
ABSTRACTSubsequent to the implantation of certain ions, the thermal stability of AlGaAs/GaAs superlattices can be reduced, enabling mixing of the layers at temperatures where they would otherwise be stable. The mixed layers have intermediate alloy composition and are of good crystalline quality. As a result this process is of great value in device fabrication where a high degree of vertical and lateral bandgap control is desirable. This paper reviews our work in understanding the mechanism of diffusion, its dependence on varilous process parameters, and potential applications in device fabrication.
