Analysis of the optical spectroscopic data and experimental results of laser irradiation revealed that absorption of an CO2 laser wavelength by the film increased with increasing the film thickness. Dielectric constant, remanent polarization, and coercive field values of the film irradiated by the CO2 laser at an annealing temperature of 850degC increased with increasing the film thickness region of 5 to 30 mum. The dielectric constant, remanent polarization, and the coercive field values of the PZT film, which irradiated by the laser, with a thickness of over 25 mum directly deposited onto the SUS substrate were over 800 and 40 muC/cm2 and under 45 kV/cm, respectively. Whereas, a displacement as the piezoelectric property of a SUS-based actuator with the PZT film irradiated by the laser decreased with increasing the film thickness. Finally, the reason and some countermeasure of deterioration of the ferroelectric and/or piezoelectric properties and the displacement for the SUS-based actuators with the PZT film irradiated by the laser are discussed.","PeriodicalId":321007,"journal":{"name":"2007 Sixteenth IEEE International Symposium on the Applications of Ferroelectrics","volume":"269 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134546328","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Authors fabricated BiFeO3 thin films with excellent performance of ferroelectric polarization by ion modification based on sol-gel technique. Some rare-earth ions, such as La3+ or Nd3+, could be substituted for Bi3+ ion in BFO crystal in order to reduce ionic defects in crystal lattices. Electrical resistivity of BiFeO3 films were improved by ion modification of rare-earth elements, as well as other Bi-based ferroelectric films like Bi4Ti3O12. Although crystal anisotropy and phase-transition temperature (Curie temperature) of these materials are generally reduced by the ion modification, it yield fully-saturated polarization (P) -electrical field (E) property to produce enhanced remanent polarization of approximately 50 muC/cm comparable or superior to conventional Pb(Zr,Ti)O3 films. We concluded that the ion modification using rare-earth elements could suppress the ionic defects that caused electrical conduction in BiFeO3 films.","PeriodicalId":321007,"journal":{"name":"2007 Sixteenth IEEE International Symposium on the Applications of Ferroelectrics","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114784070","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
