Phase composition of 0.7Pb(Mg1/3Nb2/3)O3-0.3PbTiO3 film deposited by radio frequency magnetron sputtering

Research output: Contribution to journalArticlepeer-review

Abstract

The 0.7Pb(Mg1/3Nb2/3)O3-0.3PbTiO3 (PMN-PT) films were prepared by radio frequency magnetron sputtering deposited on Pt/Ti/SiO2/Si substrate. The paper aims to study the effect of sputtering gas and the effect of annealing temperature on perovskite phase formation. Phase compositions were analyzed by X-ray diffraction and the surface morphologies of the films were characterized by scanning electronic microscopy. The polarization behavior of PMN-PT films was measured using the Radiant Technologies RT6000 ferroelectric test system. The results indicate that the appropriate sputtering gas contribute to the formation of pure-perovskite phase at the appropriate post-annealing temperature.
