掺杂的

With the Eu doping level increased to more than 1mol%, the content of B-site occupancies is increased and acceptor doping is to be dominant.

当Eu含量低于1mol％时，Eu在PZT晶格中主要占A位，起施主掺杂作用；随着Eu含量的增加，其在PZT晶格中占据B位的比例逐渐增多，受主掺杂作用逐渐增强。

It was shown that the improvement of electric properties in 1%Eu-PZT can be attributed to Eu donor doping, which decreases the concentration of defects such as oxygen vacancies and holes, while the degradation in fatigue and leakage current properties shown in the films with more than 1mol% Eu dopant results from the apparently dominant acceptor doping, which increases the concentration of oxygen vacancies and holes.

结果表明，1mol％Eu施主掺杂，可以减少氧空位以及空穴等缺陷浓度，因此1％Eu-PZT薄膜的极化疲劳和漏电流特性得到明显改善；高于1mol％Eu的受主掺杂作用使薄膜中氧空位以及空穴等缺陷浓度增加，导致PZT薄膜电学性能恶化。

But so far as the doped quantity of MoOs less than 5%, the abrupt electrical resistance change of the doped film still can reach 2 orders of magnitude, and commonly cant affect its application, so it is hopeful that temperature of the abrupt electrical resistance change can be reduced to room temperature scope.

不过只要MoO3掺杂量不高于5％时，掺杂薄膜的电阻突变仍可保持2个量级以上，一般不影响其使用功能，因此有望使电阻突变温度降至室温范围。
