    Abstract

    To conclude, the InAs/GaAs QD devices display radiation-tolerant DC characteristics despite high total dose of gamma radiation. No permanent ionising damage to the III-V compound semiconductor devices has been observed. The off-state leakage current is not worsened even when the device is continuously irradiated by gamma radiation. The results show great promise of InAs/GaAs QD structure for realization of IR photodetectors with low noise floor and high reliability in radiation environments.
