我看到关于ZnO的文章中，运用SAED时写的：
The selective area electron diffraction (SAED) pattern taken from dot-circle indicated part is shown in the inset of Fig. 3a. Diffraction
circles, which are composed of diffraction spots, can be indexed to the wurtzite structure with phase purity

问：用SAED分析ZnO属于纤锌矿型，是不是欠妥呀？我个人认为应该用XRD更为合适，不知道我这样理解是否正确？但是我又常在论文中看到说某个SAED图像表示材料的此类性质，我搞不懂了，这样做合适吗，如果可以，那应该如何运用SAED来分析呢？请各位老师讲解一下。
