Abstract

We have demonstrated that it is possible to regrow amorphous layers created by high dose As implantation in GaAs by thermal annealing in order to obtain arsenic precipitates distributed in a GaAs matrix similarly to that observed in low temperature GaAs. The characteristics of the As precipitates can be monitored through appropriate selection of the implantation and annealing conditions. Electrical measurements show that dielectric-like resistivity of surface or buried GaAs layers can be obtained by this method. Results on the growth of epilayers on these semi-insulating regions are also reported.
