dc.description.abstract | The microstructure, domain structure and piezoelectric response in lanthanide rare-earth ion (Ln) substituted BiFeO 3 (BFO) thin films are investigated systematically. Although most of the peaks in the x-ray patterns of the rare-earth-substituted BFO films are consistent with the rhombohedral crystal structure, the patterns of the Ce-, Eu- and Yb-doped samples indicate that the films contain a small amount of tetragonal impurity phase. The piezoelectric properties are enhanced due to the increased relative Bi-O displacement and the rotation of FeO 6 octahedra. Meanwhile, the domain structures of BFO films become more homogeneous by inserting Ln ions. Furthermore, the piezoresponse properties are improved by introducing Ln ions, which is attributed to the variation of ionic strength of bands between Ln ions and O ions caused by chemical modification and a lower symmetry structure © 2012 IOP Publishing Ltd. | |
