Abstract Details

2008, Master of Science, Ohio State University, Nuclear Engineering.
SiC piezoresistive pressure sensors were developed by NASA Glenn Research Center GRC) for operation in high temperature environments. SiC's wide band gap and good radiation resistance make SiC piezoresistive pressure sensors potentially suitable for use in high radiation environments. In this thesis the degradation of SiC piezoresistive pressure sensors in a Wheatstone bridge configuration is evaluated in gamma and mixed neutron/gamma radiation fields. The performance of a Si piezoresistive pressure sensor in a Wheatstone bridge configuration was also evaluated in the same radiation fields for comparison. The degradation of the performance of the Si and SiC pressure sensors was evaluated by comparing the voltage response of the sensors to pressure before, during and after irradiation. There was noticeable degradation to the voltage response of the sensors. The change in the performance of the SiC pressure sensor due to radiation was compared to measurements of the effects of temperature on the sensor performance as determined by NASA GRC. The effect of radiation on the SiC sensor's performance was very similar to the effect of temperature on the SiC sensor's performance.
