Abstract
Oxygen ions with 40 keV energy and doses of 1 × 1012 to 5 × 1014/cm2 were implanted into ferroelectric Pb(Zr,Ti)O3 (PZT) thin films. X-ray diffraction patterns show that no obvious difference appears in the crystalline structure of PZT films before and after implantation; however, measurement of electrical properties shows that both remanent polarization and dielectric constant of the film decrease with increase of the implanted ion dose. The PZT film will completely become a linear dielectric if the implanted ion dose increases to 5 × 1014/cm2. A possible mechanism for the loss of remanent polarization after ion implantation is proposed.
