摘要
perovskite 微观结构的运输性质上的氧空缺的效果理论上被学习。与相比计算、测量我 V 曲线，电子传导与甚至在氧 nonstoichiometry perovskite 异种结构起一个重要作用，这被揭示做洞或未做的材料由于氧空缺。另外，有前面、反向的偏爱的氧化物异质接面的传导特征上的氧空缺集中和温度的影响的详细理解被计算获得。
Effect of oxygen vacancy on transport property of perovskite microstructures is studied theoretically. Compared with calculated and measured I-V curves, it is revealed that electron conduction plays an important role in the oxygen nonstoichiometry perovskite heterostructures even with hole-doped or un-doped material due to the oxygen vacancies. In addition, a detailed understanding of the influence of oxygen vacancy concentration and temperature on the conduction characteristics of oxide heterojunction with both forward and reverse biases is obtained by calculation.
