Abstract : Lead zirconate titanate (PZT) based thin films play a key role in a wide variety of applications due to its ferroelectric, piezoelectric, and pyroelectric properties. This work provides information on the effects of 60Co radiation at different total ionization doses (TID) on theferroelectric, dielectric, and piezoelectric properties of PZT PiezoMEMS actuator devices with two different top electrodes. Overall, the devices with IrO2 top electrode were less impacted by the irradiation compared to the Pt top electrode devices.
