The samples were prepared by conventional ceramic technique, using p.a. purity raw materials. The mixed powders were sintered at temperatures between 1050-1300degC. Poling was done in fields of about 70 kV/cm. Density and coupling factors of the samples were determined as a function of sintering temperatures, and doping level. Temperature dependence of the main piezoelectric characteristics was also investigated for temperatures as high as 500degC. A Curie point of 450degC, a low dielectric constant (<140) and a large electromechanical anisotropy (the radial mode is nearly inexistent, at room temperature and the thickness coupling factor is about 0.4) were found. These enhanced properties make such ceramics very attractive for high temperature and high frequency transducers applications","PeriodicalId":40779,"journal":{"name":"Teatro e Storia","volume":"42 1","pages":"271-274 vol. 2"},"PeriodicalIF":0.1,"publicationDate":"2005-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91310143","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}

This is called the Zero-TC (ZTC) point. By considering two different types of MOSFET models, a strong inversion and an unified one, it can see that both of them indicated the position of the ZTC point close to the measured one (sec Table 1). As this paper indicates, it is normally to presume that the larger value obtained with the unified model is due to the sub threshold component of the drain current. This is because the strong inversion model does not take it into account. Unlike this model, the unified one considers the drain current as a sum of the diffusion current, preponderant in weak inversion, and the drift current, which governs the strong inversion region. Because the ZTC point is somewhere between these two regions, it is normally to presume that the diffusion current has an influence on it. The paper will answer to this problem and will try to explain the results","PeriodicalId":40779,"journal":{"name":"Teatro e Storia","volume":"12 1","pages":"401-404 vol. 2"},"PeriodicalIF":0.1,"publicationDate":"2005-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87513736","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}
