摘要

本文采用一种具有代表性的图形化方法来估计多晶材料的晶界势垒。用于确定捕获密度态的方程与层中掺杂浓度密切相关。结果表明，该密度是估计最大势垒值的关键参数。这个参数很大程度上取决于晶粒尺寸，因此也取决于晶界宽度。热离子电流所代表的传导(或输运)性质和有效迁移率也证明了这种相关性。所得结果与前人的实验测量值吻合较好。

POTENTIAL BARRIER ESTIMATION WITH A GRAPHICAL METHOD

In this work, a representative graphical method was used to estimate the potential barrier at grain boundaries in polycrystalline materials. The used equation for the determination of trapping density states is closely related to the doping concentration in the layer. The obtained results showed that this density is a crucial parameter for estimating the maximum barrier value. This parameter strongly depends on the grain size and, consequently, on the grain boundary width. The conduction (or transport) properties represented by the thermionic current and the effective mobility also prove this dependence. Also, the obtained results are in good agreement with the experientially measured values from previous works.
