Abstract

The results of an experimental study of the real structure of thin films of κ-phase gallium oxide are reported. It has been established by electron backscattering diffraction in a scanning electron microscope and by transmission electron microscopy that gallium oxide single microcrystals consist of three types of rotating domains of the orthorhombic symmetry, which are rotated relative to each other around the growth axis by an angle of 120°. Single-crystal domains are characterized by a high density of straight antiphase boundaries, which, when intersecting, form a significant fraction of the domain wall structure.

氧化镓κ相中的畴界和反相界结构

摘要报告了对κ相氧化镓薄膜真实结构的实验研究结果。通过扫描电子显微镜中的电子反向散射衍射和透射电子显微镜，确定了氧化镓单微晶由三种类型的正交对称旋转畴组成，这些旋转畴围绕生长轴相对旋转 120°。单晶畴的特点是高密度的反相直线边界，当它们相交时，形成畴壁结构的重要部分。
