| Research Abstract |
Piezoelectric films are very important component for MEMS applications. However, its piezoresponse was smaller than expected one from bulk materials. We found the giant piezoelectricity along {111} direction in MPB-composition PZT. In the present study, the purpose of the present study is the following issues.
1.Investigation of the origin of the large piezoresponse.
2.Investigation of the piezoresponse without PZT.
As results, the following results were obtained.
1)(100)-/(001)- oriented films with (100) volume fraction less than 50% was obtained. This film shows large d_<33> value of 400 and its origin is considered to be the domain switching.
2)Pb(Mg_<1/3>Nb_<2/3>)O_3-PbTiO_3 [PMN-PT] films with large PT content were epitaxially grown. Phase change between tetragonal and rhombohedral phases was shifted in case of films. The PT content showing maximum piezoelectric response was found to be also changed.
3)Pb(Zn_<1/3>Nb_<2/3>)O_3-PbTiO_3 [PZN-PT], which reported to show the maximum piezoresponse in bulk, was first succeeded in film form.
