本文通过正电子湮没寿命谱分析了ZrO_2材料电导率σ与稳定剂含量的关系,研究表明材料中的“有效空位量”是决定σ的关键因素,解释了σ随稳定剂含量的变化规律
In this paper, the relationship between the conductivity σ of the ZrO_2 material and the content of stabilizer is analyzed by positron annihilation lifetime spectrum. The results show that the “effective vacancy amount” in the material is the key factor to determine σ and the variation of σ with the content of stabilizer
