Abstract The dielectric properties of the bipolar SrTiO3/BaTiO3/SrTiO3 structures synthesized by pulsed laser sputtering on a single-crystal SrTiO3 substrate doped with Nb with a buffer conducting oxide sublayer of LaSrCoO3 are studied. It is shown that the structure has a transition temperature to the ferroelectric state approximately equal to 320°С. The transition into the polar phase has all the features of a second-order phase transition. The indicated structures are characterized by the presence of an internal field entirely associated with the presence of a substrate.

基于钛酸钡的层状结构的性能
摘要 研究了在掺杂有 Nb 的单晶 SrTiO3 衬底上通过脉冲激光溅射合成的双极 SrTiO3/BaTiO3/SrTiO3 结构的介电性能,该衬底具有 LaSrCoO3 缓冲导电氧化物子层。结果表明,该结构向铁电态的转变温度大约等于 320°С。转变为极性相具有二阶相变的所有特征。所示结构的特征在于存在与底物的存在完全相关的内部场。
