Sensors capable of reliable detection of hydrogen gas concentration are designed and fabricated using intrinsic diamond and doped diamond films in a MIS structure. The performance of the diamond-based gas sensor in radiation environments has been characterized by I-V measurements at room temperature. High sensitivity to hydrogen and extreme hardness to total ionizing radiation doses have been observed; the minimal change in gas-sensing characteristics at 10 MRAD is demonstrated experimentally. Analysis of the current transport mechanism, ideality factor and apparent barrier height confirm the radiation insensitivity of diamond-based MIS hydrogen sensors.
