Irradiation of semi-insulating GaAs by fast neutrons results in the creation of arsenic antisite defects. Photoresponse measurements reveal that the carrier lifetime is reduced by the irradiation. The lifetimes scale inversely with the amount of singly ionized arsenic antisites which therefore is the main carrier trapping center and lifetime killer in irradiated GaAs. The density of charged arsenic antisites also determines the charge collection efficiency of Schottky diodes made of GaAs.
