Abstract

This paper describes a high-energy electromagnetic wave radiation detection device using zinc oxide (ZnO) based Film Bulk Acoustic-Wave Resonator (FBAR). The resonant frequency of the FBAR decreased after gamma radiation, with the peak sensitivity of 9.3 kHz/krad and minimum detectable dosage of 218 rad occurring at the lowest experimental dose of 20 krad (all dosages are calibrated with ZnO), while the sensitivity decreased with increasing total ionizing dosage. The incident radiation generated charges that was trapped near the ZnO-silicon nitride (SiN) interface, which increased the plate capacitance of the FBAR, resulting in the decrease of resonant frequency.
