Image acquisition is accelerated from several minutes for standard piezo force microscopy to as fast as a fraction of a second for HSPFM. Movies of consecutive images during in-situ domain switching therefore allow high spatial and temporal resolution, with less than 500 nanosecond poling per pixel achieved. The influence of individual defects on domain nucleation, growth mechanisms, switching speed, and switching energy are therefore uniquely apparent.","PeriodicalId":228914,"journal":{"name":"2008 17th IEEE International Symposium on the Applications of Ferroelectrics","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127952858","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}

To be integrated into commercial products; however, a lead-free replacement must be fabricated using common industrial techniques while maintaining dielectric properties equivalent to the current lead-based systems. Texturing has been shown to dramatically enhance the dielectric properties of lead-free materials such that several potential systems are now being considered as replacements for the current lead-based materials. In this work, a large degree of texturing has been introduced to bismuth titanium oxide bulk samples through the process of screen printing large, plate-like seeds in a matrix of equi-axial powder. The degree of texturing achieved gives rise to a high probability of excellent dielectric properties, making textured bismuth titanate a viable replacement for commercial lead-based dielectrics.","PeriodicalId":228914,"journal":{"name":"2008 17th IEEE International Symposium on the Applications of Ferroelectrics","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132348543","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}

The diectric properties of BSBT-KBTx ceramics were investigated as a function temperature and frequency. The BSBT-KBTx ceramics showed high dielectric permittivity (> 1000 @RT) and low dielectric loss over the temperature range from 100 ~ 300°C with a flat temperature coefficient (TCC). In addition, BSBT-KBTx ceramics were observed to possess a dielectric relaxation at temperatures (> 300 K). Polarization measurements as a function of electric field showed high energy storage densities with 1.8 J/cm3 at 120 kV/cm.

Samples were all sintered at 900°C for 6 hours in PO2 = 5.38×10¿12 atm. With 3.0, 4.0wt% PbO excess addition, we note that density, micro-structure and permittivity are similar and there is a high electro-mechanical performance for example, the high field piezoelectric d33 was ~480pm/V. However, there is some decrease in d33 after the sintering in low PO2 and Rayleigh coefficients shows PO2 to slightly suppressing both the intrinsic and extrinsic contribution to piezoelectric properties.
