摘要
Semiconducting TiO2 displays non-volatile multi-state, hysteretic behavior in its I-V characteristics that can be exploited as a memory material in a memristive device. We exposed memristive TiO2 devices in the on and off resistance states to 45 Mrad(Si) of similar to 1-MeV gamma radiation and 23 Mrad(Si) of 941-MeV Bi-ions under zero bias conditions and none of the devices were degraded. These results suggest that TiO2 memristive devices are good candidates for radiation hard electronics for aerospace.
