Abstract

The contrast observed in the (0001) HREM images of MoS2 are interpreted with a model based on rotational moiré patterns. Computer-simulated images show that rotations of two supercells by angles of 3, 5, 8, and 16 degrees around their centers reproduce the contrast observed in the experimental images. The calculations suggest that these rotations occur between the sulphur layers of the MoS2 structure.

摘要

在二硫化钼的（0001）高分辨电子显微镜图像中观察到的对比度，用基于旋转莫尔条纹图案的模型进行了解释。计算机模拟图像表明，两个超晶胞围绕其中心旋转3度、5度、8度和16度时，会重现实验图像中观察到的对比度。计算结果表明，这些旋转发生在二硫化钼结构的硫层之间。
