摘要: 采用透射电镜高分辨反射电子衍射,扫描电镜形貌观察,X射线衍射等不同方法测试了不同Mg含量的N型氮化镓薄膜的结构。几种测定方法的比较表明,高分辨反射电子衍射是确定厚衬底的薄膜结构的快速而简便的方法,材料的杂质和缺陷是影响其光电导性质的重要因素。Abstract: The structural properties of Mg doped GaN films with different Mg concentrations deposited by MOCVD have been measured by TEM with high resolution reflective electron diffraction, SEM and X ray diffraction. The obtained results show that the high resol
