本文研究了空位有序TiO（x）中的取向畴。透射电子显微镜分析显示，共存的12个可能的TiO（x）单斜畴变体，这是由钛和O空位有序的α-单斜相转变引起的。群论预测的这12个单斜结构域变体可能是随机排列的。此外，几个小时的电子束辐照可以导致TiO（x）中的空位有序-无序转变（即单斜相到立方相的转变）。我们的研究结果揭示了TiO（x）纳米结构的结构特征，从而有助于相关纳米结构的制备和设计。
This paper presents a study on orientation domains in the vacancy-ordered titanium monoxide TiO(x). Transmission electron microscopy analysis revealed the co-existence of 12 possible TiO(x) monoclinic domain variants, which are induced by the cubic-to-monoclinic phase transition attributed to the Ti and O vacancy ordering. These 12 monoclinic domain variants which are predicted by group theory might be randomly arranged. Furthermore, several hours of electron beam irradiation can lead to the vacancy ordering-disordering transition (i.e. monoclinic-to-cubic phase transformation) in TiO(x). Our results shed light on the structural characteristics in TiO(x) nanostructures and thus contribute to the fabrication and design of the related nanostructures.
