摘要
Lead zirconate titanate piezoelectric ceramics have important applications in space and aerospace technology,but the effect and physical mechanism of charged particle radiation on their performance yet to be clarified.In this study,we characterized PbZr_(0.52)Ti_(0.48)O_(3)(PZT)thin films,and changes in the ferroelectric properties of the films before and after electron and proton irradiation were investigated.The natural and heat treatment recoverability of the ferroelectric properties were studied,and the damages and mechanisms of different types of radiation in PZT films were also investigated.The results show that,in addition to ionization damages,electron irradiation causes certain structural damage on the PZT film,and the large structural damage caused by proton irradiation reduces drastically the ferroelectricity of the PZT film.
