Ion implantation of Si in semi-insulating In0.53Ga0.47As:Fe was discussed. Electrical activation of more than 100%, a broad implant profile and an average electron mobility of 3000 cm2/Vs are observed in layers implanted with a dose of 2 × 1013 cm−2 at 260 keV and annealed at 670°C for 15 min. The results of photoluminescence measurements are also presented.
