本文首次对ZnO系陶瓷材料的晶粒电阻率(包括载流子浓度与迁移率)与各种因素的关系进行专门的研究,所用方法及结果对类似材料的研究亦将有重要的启示作用。 本文分别用高频阻抗分析法和红外反射光谱法测量了纯ZnO以及Co_2O_3、Al_2O_3等不同掺杂量ZnO电阻片的晶粒电阻率和晶粒载流 This article for the first time on the ZnO ceramic material grain resistivity (including carrier concentration and mobility) and various factors of the relationship between the special research, methods and results of similar materials research will also have important implications. In this paper, the high-frequency impedance analysis and infrared reflectance spectroscopy were measured pure ZnO and Co_2O_3, Al_2O_3 and other doped ZnO resistivity of grain resistivity and grain current
