Abstract
The electron mobility characteristics of a ZnMgO/ZnO heterostructure are systematically investigated by an ensemble Monte Carlo method. Screening effects are included in all electron scattering mechanisms. The mobilities are calculated for a temperature range of 4 to 300 K and Mg contents ranging from 8.5 to 44%. In this range, dislocation scattering (DS) and interface roughness scattering (IFR) are highly effective for low and high values of Mg compositions, respectively. Screening effects must be considered in scattering mechanisms to achieve a reasonable agreement with existing experimental results. Our findings could be significant for the design and optimization of ZnO-based devices.
具有屏蔽效应的 ZnMgO/ZnO 异质结构的迁移特性
摘要 采用集合蒙特卡罗方法系统地研究了氧化锌/氧化镁异质结构的电子迁移率特性。所有的电子散射机制都包含了屏蔽效应。计算了温度范围为 4 至 300 K、镁含量为 8.5% 至 44% 的迁移率。在这一范围内，位错散射（DS）和界面粗糙度散射（IFR）对低镁含量和高镁含量分别非常有效。散射机制中必须考虑屏蔽效应，才能与现有实验结果达成合理一致。我们的发现对氧化锌基器件的设计和优化具有重要意义。
