摘要
从电热转换元件的电毁现象出发,利用膜材料电性能的各向同性的性质,建立了一维晶粒列模型,给出了晶粒列模型的平衡态能带图和带尾态分布;分析了电子在越过晶间势垒时受到的散射情况.根据带尾态的分布给出了晶粒子大小与材料电导的关系.
The paper begins at electric ruin phenomenon of the electric heating converter, using electric isotropical properties of the nesa sets up one-dimensional grain line model, and gives a equilibrium energy band diagram and band tail states profile of grain line model. The moving and scatter of electrons are analyzed when they crossover grain boundary barrier layer. Based on the resultant distribution of the band tail states the relationship is given between grain size and conductivity of material.
