摘要
系统地研究了施主掺杂对多晶SrTiO_3、(Sr、Ba)TiO_3微观结构和介电性能的影响.SEM观察表明:掺杂不同施主,对多晶SrTiO_3晶粒生长起着不同的作用.施主掺杂量影响多晶SrTiO_3、(Sr、Ba)TiO_3晶粒的半导化程度及试样介电特性.
In this paper, the effects of donor - doping on microstructures and dielectric properties of multicrystals SrTiO3、(Sr、Ba)TiO3 have been studied systemalically. SEM observation shows that different donors doped have different influence on the grain growth of SrTiO3 multicrystal. The donor doping quantity affects the grains semiconducting level of SrTiO3(Sr、Ba) TiO3 multicrystals and dielectric characteristics of samples.
