本发明提供了一种基于几何相位分析的原子尺度变形场两项梯度解耦方法, 其包括:(1)通过高分辨透射电子显微镜图像获取晶体变形后的原始数据;(2)对原始数据进行傅里叶变换以获得倒易空间信息, 选择不同晶向的倒易空间信息中的衍射斑点进行逆傅里叶变换以得到局部晶格的相位信息, 基于相位信息得出晶粒内部的原子位移场;(3)将原子位移场分解成一阶仿射位移梯度张量与二阶非仿射位移梯度张量并对其分别进行分解后得到各自基本局部化事件的变形分量;(4)定义原子尺度基本局部化事件的参与度, 分析微观缺陷演化的原子尺度物理机理。

通过材料配方中掺杂不同的TiO2探究其对ZnO压敏电阻综合电气性能及退化行为的影响。实验对成品的晶相组成、微观结构、综合电学性能等进行了测试与表征。研究发现当掺杂量为0.4%(摩尔分数,下同)时的样品E4体现了整体较优的表现,其电位梯度由E0的180.2 V/mm降低至147.3 V/mm,α=83.8,IL=0.38 μA。随着20次20 kA的电流冲击,电位梯度均呈下降的趋势,其中掺杂了TiO2的样品中E4表现最佳,和分别为-5.64%和-4.71%,老化系数Kct值为0.75,功耗降低程度较大 ...
