摘要：
High dose As implantation in GaAs followed by annealing at 600 degrees C results in the formation of semi-insulating GaAs layers. These layers are relaxed with a homogeneous distribution of metallic As precipitates similarly to what is observed in GaAs grown by molecular beam epitaxy at about 200 degrees C (LT-MBE-GaAs), after annealing at 600 degrees C. By selecting the implantation parameters it is possible to adjust the thickness of the subsequent SI layer and to monitor the amount of excess As in the crystal. By selecting the annealing temperature it is possible to fabricate either a material very similar to the as-grown LT-MBE-GaAs or a material similar to annealed LT-MBE-GaAs.
