Electron-beam crystallization of amorphous films of Yb₂O₂S was studied by the methods of transmission electron microscopy “in situ” with video registration of structural changes. The kinetic curves, demonstrating the dependence on time of the crystals density and of the fraction of the crystalline phase was obtained with the help of frame-by-frame analysis of the video. The formation of the polycrystalline film occurs at a constant crystal growth rate and at a constant intensity of nucleation of crystallization centers, which corresponds to α-version of the Kolmogorov's model. The phase transformation in amorphous films of Yb₂O₂S occurs in accordance with the island polymorphous crystallization mode with the relative length δ₀≈ 1030. At small layer thicknesses of Yb₂O₂S (d ≤ 20 nm) the effect of stabilization of the amorphous state was observed.

通过透射电子显微镜“原位”和结构变化的视频配准的方法，研究了Yb ₂ O ₂ S非晶膜的电子束结晶。借助于视频的逐帧分析，获得了动力学曲线，表明了晶体密度和晶相分数对时间的依赖性。多晶膜的形成以恒定的晶体生长速率和恒定的结晶中心成核强度发生，这对应于柯尔莫哥洛夫模型的α-转变。Yb ₂ O ₂ S非晶膜中的相变是根据具有相对长度δ的岛型多晶结晶模式发生的。₀ ≈1030。在镱的小的层厚度₂ ö ₂ S（d ≤20纳米）的无定形状态的稳定化的效果进行了观察。
