Deep traps study of radiation-damaged semi-insulating GaAs detectors introduced by neutrons
Original language description
Neutron detectors based on bulk semi-insulating (SI) GaAs represent an interesting and perspective solution due to its relatively high resistance against neutrons. Therefore SI GaAs material seems to be an excellent candidate for fabrication of a neutronimaging detector. Set of detectors based on SI GaAs material was bombarded with various integral neutron fluencies (10(11)-10(15) n cm(-2)). The performance of detectors was evaluated via measured spectra of Am-241 radionuclide sources. From the resultsa significant worsening in detection ability was observed at fluencies exceeding (over) similar to 10(13) n cm(-2). These observations are explained by lattice defects in the base SI GaAs material or in the overall detector structure (electrode interfaces, surface) introduced by neutrons. Photo-induced current transient spectroscopy was used to determine changes in deep level states of bulk SI GaAs base material.
